Aldehyde insertion into a platinum hydride and subsequent nucleophilic attack of the alkoxide at phosphorus: Platinum-alkoxide/phosphorus-aryl metathesis

Article abstract of DOI:10.1021/om00158a002

R(Ph₂PO)(Ph₂POH)₂H (1) was treated with o-(diphenylphosphino)benzaldehyde to give a cyclic platinum alkoxide (2). The latter rearranges to the new product 3 (Scheme I), containing 1-phenyl-3H-2,1-benzoxaphosphole and a phenyl group coordinated to platinum, via a nucleophilic attack at the coordinated phosphorus center by the alkoxy group, followed by a shift of a phenyl group from phosphorus to platinum. The crystal structure of 3 has been determined.
