Late Transition Metal Complexes of a Coumarin-Functionalized Ditertiary Phosphine

Abstract

The synthesis of a new coumarin-modified ditertiary phosphine is reported along with three square-planar Pd^II and Pt^II complexes. All compounds have been characterised by ³¹P¹H and ¹H NMR spectroscopy, FT–IR spectroscopy and microanalysis. Furthermore a single crystal X-ray structure determination of one of these complexes has been undertaken.
