1977 Reactions of bis(hexamethylbenzene)iron(0) with carbon monoxide and with unsaturated hydrocarbons Weber, Sharon R. Journal of Organometallic Chemistry ; 127 (1977), 1. - S. 45-54 Thermal decomposition of bis(hexamethylbenzene)iron(0) in the presence of carbon monoxide yields a novel carbonyl iron complex, [C<sub>6</sub>(CH<sub>3</sub>)<sub>6</sub>]Fe(CO)<sub>2</sub>. The cyclohexadiene complex [C<sub>6</sub>(CH<sub>3</sub>)<sub>6</sub>]Fe(C<sub>6</sub>H<sub>8</sub>) is obtained from reaction of bis(hexamethylbenzene)iron(0) with either 1,3-cyclohexadiene or benzene, and the yield is much greater in the presence of hydrogen gas. Interaction of bis-(hexamethylbenzene)iron(0) with 2-butyne induces a catalytic cyclotrimerization to give more hexamethylbenzene. Kinetic and isotope distribution studies indicate that the primary step in these reactions is not a direct loss of one ring ligand, but rather an insertion of the iron center into one of the ligand methyl C-H bonds, leading to a benzyl hydride complex species. Mechanisms for the subsequent reactions of this iron hydride species are proposed. 2013-07-25T08:31:42Z deposit-license eng Brintzinger, Hans-Herbert Weber, Sharon R.
