N2 - The reaction of the phosphinidene complex [Cp*P{W(CO) 5}2] (1a) with secondary and tertiary phosphines, respectively, proceeds via W(CO)5 elimination to form the phosphoranylidene complexes [{W(CO)5}(Cp*)P-P(H) iPr2] (2), [{W(CO)5}(Cp*)P-PMe iPr2] (7), and [{W(CO)5}(Cp*)P-PEt 3] (9). Other novel types of products, the phosphine-coordinated bridged parent phosphinidene complexes [{W(CO)5}2(H)P- PMeiPr2] (6a) and [{W(CO)5}2(H)P- PEt3] (8a), are obtained by elimination of 1,2,3,4- tetramethylfulvene. The latter reaction path is predominantly found for the arsinidene complex [Cp*As{W(CO)5}2] (1b) to yield [{W(CO)5}2(H)As-PHiPr2] (4) upon reaction with HPiPr2 and, with tertiary phosphines, the products [{W(CO)5}2(H)As-PMeiPr2] (6b) and [{W(CO)5}2(H)As-PEt3] (8b). If a secondary phosphine coordinates to a bridged parent pentelidene complex, Cp*H elimination occurs to form either HP[PiPr 2{W(CO)5}]2 (3) or the phosphine-substituted diarsene complex W(CO)5[AsPiPr2{W(CO) 5}]2 (5).
