The catalytic activity of the complex Fe(η6-CHT)(η4-COD), (CHT = 1,3,5-cycloheptatriene; COD = 1,5-cyclooctadiene), 1, has been evaluated in some reference reactions such as the hydroformylation of 1-hexene and styrene and the cyclotrimerisation of a wide range of terminal and internal acetylenes. The title complex has been found to be a convenient catalytic precursor and it resulted more active than other iron catalysts in the investigated reactions.
Electrochemical Oxidation of Allenic Hydrocarbons in Acetonitrile
Becker, James Y.,Zinger, Baruch
, p. 395 - 402 (2007/10/02)
The anodic oxidation of a variety of alkyl-substituted allenes, terminal and internal ones, has been investigated in acetonitrile. All compounds studied were found to undergo 2e(-) oxidation followed by nucleophilic attack by acetonitrile and water molecules, to form products containing at least two of the following functional groups, C=C, NHCOCH3, C=O, and OH.The effect of various parameters (concentration, electrolyte, oxidation potential, temperature, and anode material) on the electro-oxidation of a model compound (nona-1,2-diene) has been studied and a general mechanistic scheme is presented and discussed.
Synthesis of Benzene Derivatives with Several Homochirally-analogous Substituents
Schoenfelder, Wolfgang,Snatzke, Guenther
, p. 1855 - 1866 (2007/10/02)
By cyclotrimerization of the corresponding acetylene derivatives some 1,3,5-trisubstituted benzene derivatives (2a - c, 8a, d) containing three identical chiral groups have been synthesized.The analogous mono- and 1,4-disubstituted products (6, 7) have be
