丁二烯二羰基[乙氧基(芳基)卡宾]铁配合物的异构化产物,C_4H_6(CO)_2FeC(OC_2H_5)Ar(1,Ar=苯基,2,Ar=对甲苯基),在己烷溶液中于-60到-40℃与三苯膦或亚磷酸三苯酯反应生成产物3-6.当1与三苯膦在己烷中于60—70℃反应时,除了生成3外,还获得双膦配位的产物7.而异戊二烯二羰基[乙氧基(芳基)卡宾]铁配合物的异构化产物与亚磷酸三苯酯反应则生成橙黄色结晶产物9,9的X射线衍射研究表明,二烯配体的键型发生了有趣的变化,即原铁配合物的π-烯丙基部分变为更有趣的含芳环的三烯体系和生成一个η~4配体以满足18电子规则.
Isomerization product of butadiene dicarbonyl [ethoxy (aryl) carbene] iron complex, C_4H_6 (CO) _2FeC (OC_2H_5) Ar (1, Ar = phenyl, 2, Ar = p-tolyl) Reaction of product 3-6 with triphenylphosphine or triphenyl phosphite in hexane at -60 to -40 ° C produces the product 3-6 When 1 is reacted with triphenylphosphine in hexane at 60-70 ° C, , But also obtained the bisphosphine coordination product 7. The isomerization of the isoprene dicarbonyl [ethoxy (aryl) carbene] iron complex with triphenylphosphite resulted in the formation of an orange-yellow crystalline product X-ray diffraction studies of 9,9 show that interesting changes have taken place in the bond types of the diene ligands, that is, the π-allyl moiety of the original iron complex has changed to the more interesting aromatic ring-containing triene system and has been generated η ~ 4 ligand to meet the 18 electronic rules.
