资源简介：
The phosphinocarbyne complex [Mo(CPPh2)(CO)2{HB(pzMe2)3}] is obtained by successive treatment of [Mo(CBr)(CO)2{HB(pzMe2)3}] with nBuLi and ClPPh2. An alternative approach to phosphorus-functionalized carbyne complexes involves the palladium-mediated reaction of [Mo(CBr)(CO)2{HB(pzMe2)3}] with diethylphosphinic acid to provide [Mo{CP(O)(OEt)2}(CO)2{HB(pzMe2)3}]. In contrast to aminomethylidynes, which typically display trigonal nitrogen centers, the phosphorus atom in [Mo(CPPh2)(CO)2{HB(pzMe2)3}] is pyramidalized.
