Abstract
The reaction of triorganylcyclotriphosphanes, (RP)3 (R = i-Pr, t-Bu), with metal carbonyl-tetrahydrofuran complexes, M(CO)5THF (M = Cr, W), yields the novel mononuclear and binuclear cyclotriphosphane-carbonylmetal complexes (RP)3M(CO)5 (R = i-Pr, t-Bu; M = Cr, W) 1-4 and (RP)3[M(CO)5]2 (R = t-Pr, M = Cr) 5, respectively. They are remarkably stable both thermally and to oxidation. Their structures have been elucidated by 31P NMR spectroscopic investigations. The cyclotriphosphane functions as a 2- or a 4-electron donor, respectively, and behaves as a Ti-acceptor comparable to Ph3P
