Reference of 1271-19-8, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1271-19-8, Name is Titanocenedichloride, molecular formula is C10Cl2Ti. In a Article，once mentioned of 1271-19-8

A CO2 complex of iron(0), Fe(CO2)(depe)2 (1; depe = 1,2-bis(diethylphosphino)ethane) has been prepared by replacement of N2 in Fe(N2)(depe)2 by CO2. The X-ray structure analysis of 1 shows that it has a eta2(C,O)-CO2 ligand in a trigonal-bipyramidal Fe geometry with some contribution of an eta1(C) mode. Reaction of 1 with R3SnCl in Et2O at -78 C gives the iron carboxylate complexes FeCl(CO2SnR3)(depe)2 (R = Me, (2a), Ph (2b)). The X-ray structure analysis of 2b shows that the CO2 fragment bridges between the Fe and Sn atoms in a mu-eta1(C):eta2(Œ,Œ + ?)-CO2 fashion. Treatment of 1 with Me3SiCl results in the removal of an O atom from the CO2 ligand to give a cationic carbonyliron(II) complex, [FeCl(CO)(depe)2]+Cl- (3a), and (Me3Si)2O. Similarly, 1 reacts with carbon electrophiles such as MeI and MeOTf to give the corresponding cationic iron(II) carbonyl complexes [FeX(CO)(depe)2]+X- (X = I (3b), OTf (3c)) and Me2O.
