Abstract

The phosphinocarbyne complex [Mo(≡CPPh2)(CO)₂{HB(pzMe ₂)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(pzMe ₂)₃}] ispyramidalized.
