Silver and gold cationic diphosphene complexes: models for protonation of the phosphorus–phosphorus double bond
Abstract
The dication, [Ar(Ag)PP(Ag)Ar]2+(Ar = 2,4,6-But3C6H2) and the monocations, [ArP
P(Ag)Ar]+ and [ArP
P(AuPEt3)Ar]+ are formed on treatment of ArP
PAr with [Ag][SO3CF3] or [Et3PAu][PF6].
