tetraphenylcyclopentadiene resulting from the coupling of two PhCCPh and of a carbene moiety, is formed; its structure has been determined by an X-ray study. In the case of aminopyridine, bidentate carbene complexes (the structure of which was confirmed by an X-ray study of (CO)4CrC (CH3)NHNC5H5) are formed, and these also react with PhCCPh to give for M = Mo, new pyrrolinones through alkyne/CO insertion
向一系列一般结构(CO)的aminocarbene配合物的二苯基乙炔的合成和反应5 MC(NHR')R(M =铬,R = CH 3中,Ph,R” =环己基,环丙基,苄基)被描述:它们通过炔烃插入,随后的1,4氢转移而导至亚胺络合物,该亚胺络合物在水解后可得到相应的酮。当R′CH 2 Ph与预期的亚胺一起时,形成由两个PhCCPh和一个卡宾部分的偶合产生的四苯基环戊二烯;其结构已通过X射线研究确定。在氨基吡啶,二齿碳烯配合物(的情况下其结构是由(CO)的X射线研究证实4 CrC(CH 3)NHNC 5 ħ5)形成,并且它们还与PhCCPh反应,通过炔烃/ CO插入,随后进行1,2氢转移,使M = Mo,生成新的吡咯烷酮。
