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.
使用烯丙基取代基的性质极大地影响使用Fe(CO)5或Fe 3(CO)12的某些取代的环己1,4-和1,3-二烯的络合过程中异构体的比率:CO 2 Me趋于以将金属引导到其被占领的表面,Ph值较小,而Me则具有抑制作用。适当取代的环己二烯给出单个立体异构体。
