Abstract

The Lewis acid/base stabilized phosphanylboranes and -arsanes [(CO)5W(H2EBH2·NMe3)] (1a: E = P; 1b: E = As) have been shown to react with the platinum(0) complex [(Ph3P)2Pt(C2H4)] under oxidative addition of the E-H bond to the platinum center. The complexes cis-[(Ph3P)2Pt(H)(-EHBH2·NMe3)W(CO)5] (2a: E = P; 2b: E = As) are formed. Complex 2a is unstable in solution at room temperature and slowly ...
