The monoesters of mono- (1a), di- (1b), tri- (1c) and tetra- (1d) ethylene glycol with 3,4,5-trisbenzoic acid (1), the polymethacrylates derived from them (2) and the complexes of both 1 and 2 with LiCF3SO3 and NaCF3SO3 self-assemble into cylindrical supra molecular architectures which exhibit a hexagonal columnar (Phih) mesophase.The generation of the Phih mesophase depends on the stabilization of this assembly by endo-recognition in the core of the cylinder (H-bonding and ionic interactions) and exo-recognition that occurs between the tapered groups and also between the cylinders (i.e., the hexagonal arrangement of the columns).The low molecular weight compounds 1 are able to complex more salt in the Phih mesophase and have larger increases in Phih-isotropic transition temperature (TPhih-i) per increase in salt concentration than the corresponding polymethacrylates 2 derived from them.Molecular modelling appears to indicate that positional and conformational restrictions imposed by both the tapered side groups and the polymer backbone are responsible for these results.Both the polymers and the low molar mass compounds have their TPhih-i shifted to lower temperatures and allow more LiCF3SO3 to be complexed with the increase in the number of oxyethylene segments present in the flexible spacer.A comparison of the difference in the effectiveness of the Li cation versus the Na cation in providing increased stabilization of the Phih mesophase does not show any significant differences between the two cations.

A simple procedure was suggested for the chromatographic analyses of bio-oils from pyrolysis of various feedstock employing different technologies. An acetonitrile solution of each bio-oil was prepared without any extraction or other sample pretreatments. Preliminary thin layer chromatography showed a large number of compounds having a broad range of retention factors (Rfs) among 0-1. Products having a retention factor over 0.9 were mainly detected by GC while some other compounds were only identified by HPLC. GC/MS-FID analysis was used to identify and quantify compounds using peak areas and relative response factors (RRFs). A new equation was proposed to estimate RRFs of compounds identified via their MS spectra when experimental RRFs were not readily available. The novel procedure was employed to characterize bio-oils from pyrolysis of wood of different source or obtained using different pyrolysis procedure. Using this RRF method guaiacol, furfural, butan-2-one, levoglucosan, acetic acid and many other compounds were quantified in bio-oil samples. Different amount of them were found as a function of the type of wood, and pyrolysis conditions adopted. For instance levoglucosan was the main compound using carbon as MW absorber however acetic acid was prevalent when a MW absorber was not employed and both of them were absent in bio-oils from classical heating. The HPLC/MS of bio-oils showed cyclohexancarboxylic acid, 1,2,4-trimethoxybenzene and 2,6-dimethylphenol among the main products present in all bio-oils. On the contrary 4-hydroxyacetophenone and (3,4,5-trimethoxy) acetophenone were present in bio-oil from pyrolysis of wood using MW oven and 2,5-furandiylmethanol when a MW oven without any absorber was employed. Cyclohexanone was present in bio-oils obtained with a thermal heating or a MW oven without any absorber.

A step-economical method for synthesis of alpha-CF2H-substituted ketones from readily available alkene feedstocks has been developed. Radical difluoromethylation of aromatic alkenes combining DMSO oxidation and photoredox catalysis is a key to the successful transformation. Electrochemical analysis, laser flash photolysis (LFP), and density functional theory (DFT) calculations reveal that N-tosyl-S-difluoromethyl-S-phenylsulfoximine serves as the best CF2H radical source among analogous sulfone-based CF2H reagents. The present photocatalytic keto-difluoromethylation has been applied to flow synthesis and easily scaled up to gram-scale synthesis within a reasonable reaction time. Furthermore, potentials of the alpha-CF2H-substituted ketones for useful synthetic intermediates are shown; e.g., synthesis of the CF2H-containing alpha-hydroxyamide with the same carbon skeleton as that of the anticonvulsant active CF3-analogue, is disclosed. Additionally, mechanistic studies are also discussed in detail.

A series of l-phenylalanine ionic liquids (ILs), l-tyrosine ILs, tertiary amino analogues and proposed transformation products (PTPs) have been synthesised. Antimicrobial toxicity data, as part of the green chemistry metrics evaluation and to supplement preliminary biodegradation studies, was determined for ILs, tertiary amino analogues and PTPs. Good to very good overall yields (76 to 87%) for the synthesis of 6 ILs from l-phenylalanine were achieved. A C2-symmetric IL was prepared from TMS-imidazole in a one-pot two-step method in excellent yield (91%). Synthesis of the l-tyrosine IL derivatives utilised a simple protection group strategy by using an extra equivalent of the bromoacetyl bromide reagent. Improvements in the synthesis of the alpha-bromoamide alkylating reagent from l-phenylalanine were achieved, directed by green chemistry metric analysis. A solvent switch from dichloromethane to THF is described, however the yield was 15% lower. Antimicrobial activity testing of l-phenylalanine ILs, l-tyrosine ILs, tertiary amino analogues and PTPs, against 8 bacteria and 12 fungi strains, showed that no compound had a high antimicrobial activity, apart from an l-proline analogue. In this exceptional case, the highest toxicity (IC95 = 125 and 250 muM) was observed towards the two Gram positive strains Staphylococcus aureus and Staphylococcus epidermidis respectively. High antimicrobial activity was not found for the other bacteria or fungi strains screened. The limitations of the antimicrobial activity study is discussed in relation to SAR studies. Preliminary analysis of biodegradation data (Closed Bottle Test, OECD 301D) is presented. The pyridinium IL derivative is the preferred green IL of the series based on synthesis, toxicity and biodegradation considerations. This work is a joint study with Kuemmerer and co-workers and the PTPs were selected as target compounds based on concurrent biodegradation studies by the Kuemmerer group. For the comprehensive biodegradation and transformation product analysis see the accompanying paper.

Finding new methods of carbon-carbon bond formation is a key goal in expanding current methodology for heterocycle formation. Because of their inherently nonplanar shape, new methods of forming sp3-rich scaffolds are of particular importance. Although there are methods for combining heterocyclization and formation of new sp3-sp3 carbon-carbon bonds, these form the carbon-heteroatom bond rather than a carbon-carbon bond of the heterocycle. Here, we show a new alkene arylallylation reaction that generates a heterocycle with concomitant formation of two new carbon-carbon bonds. Furthermore, we demonstrate that this process occurs through an isohypsic (redox neutral) mechanism. Overall, this carboallylation reaction gives a new route to the synthesis of 3,3-disubstituted heterocycles.
