Synthesis and thermolysis of dimethylbis(trialkylphosphine)platinum(II) complexes in which the phosphine ligands contain adamantyl, adamantylmethyl, and methyl groups

Article abstract of DOI:10.1021/om00145a027

This paper describes syntheses of (1-adamantylmethyl)dimethylphosphine (1), bis(1-adamantylmethyl)methylphosphine (2), tris(1-adamantylmethyl)phosphine (3), 1-adamantyldimethylphosphine (4), di-1-adamantylmethylphosphine (5), and the platinum complexes L₂PtMe₂ (7, L = 1; 8, L = 2; 9, L = 4). Thermal decomposition of 7 and 8 yields cyclometalated products; 9 decomposes by a complex, poorly defined route. The paper discusses factors that render phosphines susceptible to intramolecular reactions.
