摘要

Abstract Catalytic dehydrocoupling of phosphines was investigated using the anionic zirconocene trihydride salts [Cp* 2 Zr (μ-H) 3 Li] 3 (1 a) or [Cp* 2 Zr (μ-H) 3 K (thf) 4](1 b), and the metallocycles [CpTi (NPtBu 3)(CH 2) 4](6) and [Cp* M (NPtBu 3)(CH 2) 4](M= Ti 20, Zr 21) as catalyst precursors. Dehydrocoupling of primary phosphines RPH 2 (R= Ph, C 6 H 2 Me 3, Cy, C 10 H 7) gave both dehydrocoupled dimers RP (H) P (H) R or cyclic ...
