Cyclopropenylidene approach to tricarbide complexes: Synthesis and structure of [M(CO){sub 5}(mu{sub 2}-C{sub 3}(OCH{sub 2}CH{sub 3} ))Fe(CO){sub 2}(Cp)] (M = Cr, Mo, W)
- Univ. of Kentucky, Lexington, KY (United States)
Diethoxycyclopropenylidene complexes [M(CO){sub 5}(C{sub 3} (OCH{sub 2}CH{sub 3}){sub 2})] (M = Cr, Mo, W) react with K[Fe(CO){sub 2}(Cp)] to give the bimetallic cyclopropenylidene complexes [M(CO){sub 5}({mu}{sub 2}-C{sub 3}(OCH{sub 2}CH{sub 3}))Fe(CO){sub 2}(Cp)], but the second ethoxide is not displaced by excess K[Fe(CO){sub 2}(Cp)]. Spectroscopic evidence ({sup 1}H NMR, {sup 13}C NMR, and IR) as well as a X-ray crystal structure determination of [Cr(CO){sub 5}({mu}{sub 2}-C{sub 3}(OCH{sub 2}CH{sub 3} ))Fe(CO){sub 2}-(Cp)] suggests that the central C{sub 3} ring has a great deal of cyclopropenium character. 46 refs., 1 fig., 1 tab.
