Silver(I) Complexes of Bisphosphines PhN{P(OC 6 H 4 C 3 H 5 - o ) 2 } 2 (1) and 2,6-{Ph 2 PC(O)} 2 C 5 H 3 N (2)

摘要

Abstract Silver complexes of two bisphosphine ligands, PhN{P(OC 6 H 4 C 3 H 5 - o ) 2 } 2 ( 1 ) and 2,6-{Ph 2 PC(O)} 2 C 5 H 3 N ( 2 ) have been described. Reactions of bisphosphines 1 and 2 with silver salts produce either mononuclear or dinuclear complexes ( 3 – 6 ) depending on the stoichiometry of the reagents and the reaction conditions. All new complexes have been characterized by spectroscopic and analytical data. The structure of spirocyclic complex, [Ag{2,6-{Ph 2 PC(O)} 2 C 5 H 3 N} 2 ][CF 3 SO 3 ] ( 6 ) has been confirmed by single crystal X-ray analysis.
