Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. Quality Control of 1,1′-Dibromoferrocene. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1293-65-8, Name is 1,1′-Dibromoferrocene

A novel polar dppf derivative possessing only planar chirality, 1?,2-bis(diphenylphosphino)-ferrocene-1-carboxylic acid (Hdpc), has been synthesised in racemic form and resolved into enantiomers via esters with d-glucose diacetonide ((Rp)- and (Sp)-3). (R p)-Hdpc was further converted to a series of N-substituted amides that were studied as ligands for Pd-catalysed enantioselective allylic alkylation of racemic (E)-1,3-diphenylprop-2-en-1-yl acetate or ethyl carbonate with malonate esters, showing high activity and good enantioselectivity (er up to 10: 90). The catalytic results were correlated with the structural data (X-ray diffraction and solution NMR) for (eta3-allyl)palladium(ii) complex (Rp)-[Pd(eta3-1,3-Ph2C 3H3){Fe(eta5-C5H 3-1-(C(O)NHCH2Ph)-2-(PPh2-kappaP)) (eta5-C5H4PPh2-kappaP)}]ClO 4 (16) as a model of the plausible reaction intermediate. A further study into the coordination properties of Hdpc led to isolation of chelate complex [PdCl2(Hdpc-kappa2P,P?)] (12). The crystal structures of rac-Hdpc, methyl ester of (Rp)-Hdpc, glycoside (R p)-3, and 12·Me2CO suggested a close structural relationship between dppf and Hdpc.
