Stepwise formation of chiral clusters viaσ3, λ4-phosphanediyl compounds of type (R)(η1-C5Me5)PMLn

Abstract

The chiral cluster (2,4,6-Bu^t₃C₆H₂O)[graphic omitted]n(CO)₄6 has been synthesized stepwise from (R)(η¹-C₅Me₅)PMn(CO)₄1(R = 2,4,6-Bu^t₃C₆H₂O) and Fe₂(CO)₉2; the rearrangement of η²-{(R)(η¹C₅Me₅)PMn(CO)₄}Fe(CO)₄3 to (R)[(η⁵-C₅Me₅)Fe(CO)₂]PMn(CO)₄4 proves to be the decisive step in this synthesis; the X-ray structure analysis of 4 and 6 are reported.
