Abstract

Addition of phosphonoacetate anions to (vinylketene)tricarbonyliron(0) complexes gave (vinylallene)tricarbonyliron(0) complexes; stereoselectivity as high as 98:2 was observed and the relative stereochemistry of the major stereoisomers was elucidated by X-ray crystal structure analysis of the major isomer of [PhCH = CHC(Me) = C = CHCO2Bu(t)](CO)3Fe0 3d, the product obtained from the reaction between [PhCH = CHC(Me) = C = O](CO)3Fe0 1a and the anion of (EtO)2P(O)CH2CO2Bu(t) 2b.
