2-Methoxyphenyl Phosphite Complexes of Platinum(0) and Nickel(0)

The compounds P(OC6H4OMe-2)3 and P(OC6H4OMe-2)(OC6H4Me-4)2 have been prepared.The platinum(0) complex 3>3> 1 can be made by the reduction of 3>2> in the presence of the phosphite or by addition of the latter to tris(η2-norbornene)platinum, and 2-C2H4)3>2> 2 by the reduction of 3>2> in the presence of ethene or by adding of phosphite to 2-C2H4)3>.The crystal structures of the ligand P(OC6H4OMe-2)3 and complex 2 have been determined and the effect of co-ordination on the conformation of the phosphite substituents is discussed.The ethene ligand in 2 is readily substituted by other alkenes and alkynes to give complexes 3-9 of the general type 2-alkene)3>2> or 2-alkyne)>P(OC6H4OMe-2)3>2>.Reduction of 2> (acac = acetylacetonate) with AlMe3 in the presence of ethene gives 2-C2H4)3>2> 10.The air-sensitive complex 3>3> 11 can be generated in solution by treatment of 2> (cod = cycloocta-1,5-diene) or 10 with the phosphite ligand.The tetrahedral complex 2>4> 12 is readily made from 2> and the phosphite.The catalytic activity of 11 and 12 for the monohydrocyanation of buta-1,3-diene is discussed in relation to similar well known catalysts and it is concluded that the methoxy groups inhibit the catalysis probably by combination of steric hindrance and weak co-ordination of the ether oxygen.
