Platinum(0) olefin complexes of a bulky terphenylphosphine ligand. Synthetic, structural and reactivity studies†‡
Abstract
A novel terphenylphosphine PMe2ArDipp2 (1) (Dipp = 2,6-iPr2C6H3) forms stable Pt(0) complexes with ethene and 3,3-dimethylbut-1-ene that behave as sources of the reactive Pt(PMe2ArDipp2) fragment. The complexes are efficient catalysts for the selective hydrosilylation of terminal alkynes.
