Nucleophilic attack on co-ordinated phosphinoacetylenes: products from the hydrolysis of cis-PdCl2(Ph2PCCCF3)2 and the X-ray structure of a 1-diphenylphosphino-3,3,3-trifluoropropen-2-olato complex

Abstract

The hydrolysis of cis-PdCl₂(Ph₂PCCCF₃)₂ proceeds via nucleophilic attack at both phosphorus and alkyne sites yielding novel complexes containing 1-diphenylphosphino-3,3,3-trifluoropropen-2-olato, diphenyl-ethoxyphosphine, diphenylphosphinous acid, and β-keto phosphine ligands; a 1-diphenylphosphino-3,3,3-trifluoropropen-2-olato species has been fully characterised by an X-ray structure determination.
