Stereoselectivity in the formation of tricarbonyliron complexes of some dihydrobiphenyls

Bandara, B.M.Ratnayake,Birch, Arthur J.,Chauncy, Brian

, p. 137 - 141 (2007/10/02)

Ratios of isomeric products in complexation of some substituted cyclohexa-1,4- and 1,3-dienes, using Fe(CO)5 or Fe3(CO)12 are significantly affected by the nature of an allylic substituent: CO2Me tends to direct the metal to its occupied face, Ph less so and Me is inhibitory.An appropriately substituted cyclohexadiene gives a single stereoisomer.
