Abstract

New cyclopropene complexes of platinum have been synthesised with a variety of bulky substituents on all positions of the cyclopropene ring. Two of these novel complexes,[Pt (3, 3- Ph 3 C 3 H 2)(PPh 3) 2] and [Pt (1, 2-Ph 2 C 3 H 2)(PPh 3) 2], have been structurally characterised by X-ray analysis. Both contain a cyclopropene ring which has remained intact upon complexation. The bond lengths within the complexes are remarkably independent ...
