reacted with copper(I) and copper(II) precursors to yield structurally characterized compounds with N-, O,N-, N,S- and O,N,S-coordination: [CuI(1-κ2O,N)(dppf)](PF6) 3(PF6), [CuI(2- κ2N,S)(dppf)](PF6) 4(PF6), [CuII(1- κN)(NO3- κO)2] and [CuII(1-κ2O,N)(NO3-κO)2] 5, and [CuII(2-κ3O,N,S)(NO3-κO)2] 7 where dppf is 1,1’-bis(diphenylphosphino)ferrocene. Spectroelectrochemistry reveals that the cations 3+ and 4+
配体N-苯基樟脑亚氨基醌1和N- (2-硫甲基苯基)樟脑亚氨基醌2与铜 (I) 和铜 (II) 前体反应生成具有 N-、O、N-、N、S- 和 O 的结构特征化合物, N,S-配位:[Cu I ( 1 -κ 2 O , N )(dppf)](PF 6 ) 3 (PF 6 ), [Cu I ( 2 - κ 2 N,S )(dppf)](PF 6 ) 4 (PF 6 ), [Cu II ( 1 - κ N)(NO 3 -κ O ) 2 ] 和 [Cu II ( 1 -κ 2 O , N )(NO 3 -κ O ) 2 ] 5和 [Cu II ( 2 -κ 3 O , N , S )( NO 3 -κ O ) 2 ] 7其中 dppf 是 1,1'-双(二苯基膦基)二茂铁。光谱电化学表明阳离子3 +和4 +表现出基于二茂铁的氧化和以樟脑亚醌为中心的还原。铜 (II) 化合物5和7表现出配位多样性
