Abstract
Ortho-lithiation of Ph 3P NPh followed by reaction with HgCl 2 gave good yields of [Hg{C 6H 4(PPh 2 NPh)-2}Cl], 3, which was characterised spectroscopically and by an X-ray crystal structure determination. This is an isomer of the product of direct mercuration of Ph 3P NPh which occurs on the N-bonded phenyl ring [J. Vicente, J.A. Abad, R. Clemente, J. Lopez-Serrano, M.C. Ramirez de Arellano, P.G. Jones, D. Bautista, Organometallics, 22 (2003) 4248]. Transmetallation of 3 with [AuCl 4] − gave the corresponding cycloaurated complex [Au{κ 2- C, N-C 6H 4(PPh 2 NPh)-2}Cl 2], with a five-membered metallocyclic ring incorporating four different elements.
