Abstract

The reaction of the η²-arylthioxophosphane complex CpCr(CO)₂(SP(H)Ar) (2; Ar = C₆H₄-OCH₃) with [CpCr(CO)₃]₂ (1) at 110°C led to the isolation of new structurally characterized complexes: hydridophosphido-bridged Cp₂Cr₂(CO)₄(μ₂-H) (μ₂-P(H)Ar) (3), bis(phosphido)- bridged Cr=Cr doubly bonded Cp₂Cr₂(CO)₂(μ₂- P(H)Ar)₂ (4), and μ₃-phosphinidene cubanes Cp₄Cr₄S₃(μ₃-PAr) (5) and Cp₄Cr₄S₃(μ₃-PAr) (5) and Cp₄Cr₄S₂(μ₃-PAr)₂ (6), together with CpCr(CO)₃H (7) and Cp₄Cr₄S₄ (9) with yields of 4, 11, 16, 32, 5, and 19%, respectively.
