Substitution effects at bridging vinyl ligands: molecular structures of where R = OEt or ferrocenyl
The two related compounds (R = OEt or ferrocenyl C5H4FeC5H5, Fc), have been prepared, the first by insertion of ethyl ethynyl ether (CH<*>COEt) into and the second by oxidative addition of ethenylferrocene (CH2 = CHFc) to respectively.Spectroscopically both compounds are similar to known related compounds with alkyl- or aryl-substituted vinyl ligands.A single-crystal X-ray structural study of each was made in an attempt to detect any structural effects of ?-donation by the substituents at the vinylgroup, such as was observed for .The latter compound has been shown to have a zwitterionic structure with an alkylidene bridge between two osmium atoms rather than the normal mu,eta2-vinyl mode of bonding.The two compounds studied here have essentially normal mu,eta2-vinyl bridges, but with some distortion towards the alkylidene bonding type, more pronounced for R = OEt.
