  PhP–PPh group bound to 1,8-positions of naphthalene: Preparation of cis isomer and synthesis of binuclear complex

  摘要：

  A thermodynamically less stable cis isomer of 1,2-diphosphacycle was prepared from the corresponding trans isomer. Diphosphine, in which a PhP-PPh bond bridges the 1,8-positions of naphthalene, 1,2-diphenyl-1,2-dihydronaphtho[1,8-cd][1,2] diphosphole (1), was first prepared according to a previously reported method, and the trans isomer of 1 was irradiated in tetrahydrofuran with UV-vis light to reach equilibrium with cis-1 in a trans: cis ratio of 1:2. When a similar photochemical conversion was carried out using a saturated hexane solution of trans-1, cis-1 was precipitated in a good yield of 94%. The configuration of cis-1 was confirmed by X-ray analysis. Both cis-and trans-1 diphosphine ligands were used for the preparation of binuclear gold complexes. The crystal structure of (mu-cis-1)-[AuCl](2) demonstrated that the two lone pairs of cis-1 are suitably directed for arrangement of the two gold centers in close proximity to each other. The two independent (mu-cis-1)-[AuCl](2) molecules in the crystal were found to form a dimer through the multiple intermolecular interaction among the gold centers. (C) 2011 Elsevier B. V.
