Synthesis and reactivity of binuclear copper(I) complexes of 2-(diphenyl-phosphino)-6-(pyrazol-1-yl)pyridine (L1). Crystal structures of [Cu2(μ-L1)2(MeCN)2][ClO 4]2

Reaction of 2-(diphenylphosphino)-6-(pyrazol-1-yl)pyridine (L1) with 1 equivalent of [Cu(MeCN)4][ClO4] resulted in the formation of [Cu2(μ-L1)2(MeCN)2][ClO 4]2 1. Complex 1 reacted with Li(C≡CPh) to give [Cu2(μ-L1)2-(μ-η 1-C≡CPh)][ClO4] 2, which underwent an alkynyl ligand-transfer reaction with [Pd(PBun3)2Cl2] to give [Cu2(μ-L1)2(μ-Cl)][ClO4] 3 and [Pd(PBun3)2(C≡CPh)Cl]. Reaction of 1 with dimethyl acetylenedicarboxylate yielded [Cu2(μ-L1)2(μ-MeO 2CC≡CCO2Me)][ClO4]2 4, the alkynyl ligand of which can easily be displaced by bis(diphenylphosphino)methane (dppm) -{Fe(η5-C to give [Cu2(μ-L1)2(μ-dppm)][ClO 4]2 5. The crystal structures of 1, 2·CHCl3·H2O and 3-H2O have been determined.

Binuclear silver(I) complexes with polydentate phosphine ligands 2-(diphenylphosphino)-6-pyridine and 2-(diphenylphosphino)-6-(pyrazol-1-yl)pyridine

The new polydentate, pyridine-based phosphine ligand 2-(diphenylphosphino)-6-pyridine (L2) has been synthesized.The reaction of L2 with resulted in the formation of the binuclear silver(I) complex 2)2(ClO4)2>, which is stabilized by significant ?-? stacking interactions between its inter-ligand pyridyl fragments.In contrast, the reaction of 2-(diphenylphosphino)-6-(pyrazol-1-yl)pyridine (L1) with gave the binuclear complex 1)2(MeCN)2>2, which exhibits a weak metal-metal interaction.
