The first transition metal cholesteryl-phosphine complexes

Abstract

Novel optically pure cholesteryl-phosphine ligands (3α-PPh₂chol and 3β-PMe₂chol) have been synthesized and were shown to form stable and highly soluble Pd(II) and Pt(II) complexes; as revealed by an X-ray analysis the (chol)P···P(chol) fragment of the square planar trans-[PtI₂(3β-PMe₂chol)₂] complex adopts a staggered arrangement (V-shape).
