Synthesis, characterisation and reactivity of the first diphosphaalkyne†
Abstract
The first diphosphaalkyne, PCC(C6H4)3CCP, has been synthesised and structurally characterised; its reaction with [Pt(C2H4)(PPh3)2] affords the complex, [{(PPh3)2Pt}2{μ-η2:η2-PCC(C6H4)3CCP}], whilst its treatment with [RuHCl(CO)(PPh3)3] yields the bis-ruthenium phosphaalkenyl complex, [{(PPh3)2(CO)ClRu}2{μ-PC(H)C(C6H4)3CC(H)P}].
