Abstract

Abstract A series of carbenerhodium (I) complexes of the general composition [(η 5-C 5 H 5) Rh (= CRR′)(L)](2 a–2 i) with R= R′= aryl and L= SbiPr 3 or PR 3 has been prepared from the square-planar precursors trans-[RhCl (= CRR′)(L) 2] and NaC 5 H 5 in excellent yields. Reaction of the triisopropylstibane derivative 2 a, which contains a rather labile Rh− Sb bond, with CO, PMe 3, and CNR (R= Me, CH 2 Ph, tBu) leads to the displacement of the ...
