Complexation behaviour of Cd with methylimino diacetic acid (MIDA) and some amino acids (alanine, glycine, aspartic and glutamic) have been investigated at DME. The formation of MXY, MXY2 and MX2Y complexes has been identified. The reduction of all these complexes has been found to be reversible and diffusion controlled, involving two electrons. The treatment of Schaap and McMasters has been used to evaluate the stability constants for all these complexes. The statistical and electrochemical effects have been discussed by using these stability constants. The positive values of mixing constants (KM) and stabilization constants (Ks) indicate that the ternary complexes are more stable than the binary complexes.

Known since 1959, ferroceneboronic acid (1) and its derivatives have been mainly used as polyol sensors and in cross-coupling reactions. However, a literature survey revealed that there is not a paper describing the full characterization of ferroceneboronic acid derivatives and that useful boron protecting groups have not been studied in the ferrocene series. Here, we present an optimized multigram-scale synthesis of the known ferroceneboronic acid (1) using a phase-switch purification process. It was furthermore functionalized to reach the diaminonaphthalene (FcB(dan), 15), anthranilamides (FcB(aam), 16; FcB(Me-aam), 17 and 18), potassium trifluoroborate (FcBF3K, 19), triolborate (FcB(triolborate), 20) and N-methyliminodiacetic acid (FcB(MIDA), 21) derivatives. Their structures were unambiguously assigned by NMR and X-ray analysis, and the data collected provided a general overview of the electronic and structural features of these compounds. From the data obtained, B(dan) and B(amm) were classified as electron-withdrawing groups, whereas trifluoroborate and triolborate behave as electron-donating groups. We report the first catalytic silylation of ferrocene C-H bonds to access di- and trisubstituted derivatives. Catalytic borylation was also attempted, highlighting a switch in regioselectivity that was unambiguously assigned by X-ray analysis.

The combination of a vinyl-substituted aromatic or heteroaromatic and an alkyl bromide or iodide leads, in the presence of Zn and a catalytic amount of an Fe(II) salt, to a net reductive coupling. The new C-C bond is regiospecifically formed at rt at the beta-site of the alkene. The coupling only occurs in an aqueous micellar medium, where a radical process is likely, supported by several control experiments. A mechanism based on these data is proposed.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

1-(Trimethylsilyl)vinyl MIDA boronate – a trifunctional C 2 building block – is prepared in only two laboratory steps and 54% overall yield starting from readily available trimethyl(vinyl)silane. The title compound undergoes orthogonal functionalization at either of the groups present in its structure, for example, iodination at the trimethylsilyl moiety, epoxidation at the double bond, and Suzuki-Miyaura coupling at the MIDA boronate.

Divergent catalytic reactions provide quick access to diverse molecular scaffolds through controlled reaction pathways by tuning the catalytic conditions, especially changing auxiliary ligands and/or counterions. This study presents a computational study of Au(I)-catalyzed regiodivergent cycloisomerizations of boron-containing alkynyl epoxides toward C2- and C3-borylated furans. The calculations clarified the mechanistic details of the reaction and the regiodivergence induced by two gold catalysts. The proposed catalytic cycle involves two major stages: ring expansion of alkynyl epoxide accompanied by B(MIDA) group migration to form a m-boron furyl heterocyclic intermediate and a formal 1,2-H or a 1,2-B migration to form a C3- or C2-borylated furan. The former is identified as the bottleneck of the reaction, which proceeds via sigma activation of the oxirane moiety rather than pi activation of the alkynyl moiety proposed in experimental work, and the latter controls the regiodivergence. Calculations show that the counterion and ligand in the gold catalyst play a less important role in the ring expansion, but they are crucial for the divergent formation of borylated furans: an OTf- counterion with an (ArO)3P ligand favors the 1,2-H migration, leading to the formation of C3-borylated furan, whereas an SbF6- anion with an IPr ligand promotes the 1,2-B migration, supporting the predominant formation of C2-borylated furan. The theoretical results rationalize the observed regioselectivity and provide key insights into the mechanism of the migratory cycloisomerization of boron-containing alkynyl epoxides.

Novel boron-containing drugs have recently been suggested as a new class of pharmaceuticals. However, the majority of current boron-detection techniques require expensive facilities and/or tedious pretreatment methods. Thus, to develop a novel and convenient detection method for boron-based pharmaceuticals, imine-type boron-chelating-ligands were previously synthesized for use in a fluorescent sensor for boronic acid containing compounds. However, the fluorescence quantum yield of the imine-type sensor was particularly low, and the sensor was easily decomposed in aqueous media. Thus, in this paper, we report the development of a novel, convenient, and stable fluorescent boron-sensor based on O- and N-chelation (i.e., 2-(pyridine-2yl)phenol), and a corresponding method for the quantitative and qualitative detection of boronic acid-containing compounds using this commercially available sensor is presented.

The study of the metal binding pattern of N-methyladenines (1-, 3-, 7- or 9-Meade) towards CuII-iminodiacetate-like chelates is addressed on the basis of XRD crystal structures of sixteen novel ternary compounds. Except for three compounds, all others feature an square-based Cu(II) coordination, type 4 + 1, and the efficient cooperation of a Cu[sbnd]N7 bond with an intra-molecular N6-H?O(coord. carboxylate) interligand interaction as the major metal-binding pattern. The three referred exceptions to this behavior are: (1) the compound [Cu(MIDA)(7Meade)(H2O)]·4H2O, which evidence the Cu[sbnd]N3 binding pattern; the (2) [Cu(IDA)(1Meade)(H2O)2]·4H2O, which molecular recognition consist in the Cu[sbnd]N9 bond and a (distal aqua)??N3(1Meade) intra-molecular interaction, within an octahedral Cu(II) center; and (3) [Cu(IDA)(9Meade)(H2O)2]·3H2O, also with a 4 + 1 + 1 Cu(II) coordination, where the Cu[sbnd]N7 bond exists along with an extremely weak N6-H?O(coord. carboxylate) interaction (3.33 A, 140.2). This former interaction is determined by packing forces that promote the participation of the N6[sbnd]H group in a ?trifurcated? H-bond. In conclusion, the cooperation between the Cu[sbnd]N7 bond (not possible for 7Meade) and the intra-molecular N6-H?O interaction is clearly favored (a) by the H-accepting role of the O-coordinated carboxylate atoms from the iminodiacetate ligands in mer-NO2 conformation and (b) in compounds where the Cu(II) atom exhibits an elongated square-base pyramidal coordination, type 4 + 1.

An enantioselective and non-oxidative methodology was developed to obtain enantioenriched cyclopropyl boronates using a diethanolamine-promoted selective decomplexation of dioxaborolane. The non-oxidative decomplexation of the dioxaborolane ligand from the cyclopropylmethoxide species formed in the dioxaborolane-mediated Simmons-Smith cyclopropanation reaction provided the enantioA-enriched CIDA-based (CIDA = N-cyclohexyliminodiacetic acid) boroA-cyclopropane in 92% yield and 95.6:4.4 er. A robustness screen has shown diethanolamine to be compatible with esters, carbamates and N-heterocycles, providing a tool to access enantioenriched cyclopropanes carrying not only base-sensitive but oxidizable functional groups as well. Diethanolamine was found to be compatible with the modified zinco-cyclopropanation reaction of allyl alcohol to remove residual dioxaborolane from the corresponding cis-N-heterocycle cyclopropylmethanol, thereby leading to improved yields.
