Abstract

Synthesis and Structure of Cyclopropenone π-Complexes with Pentacarbonyliron(0) and Hexacarbonyltungsten(0). Hydrophosphorylation of Cyclopropenone in the Transition Metal Coordination Sphere. -The reaction of the title cyclopropenone metal complexes [cf. (I)] with HPO(O-Et)2 gives rise to the corresponding α-hydroxyphosphonates [cf.(III)], whereas hydrophosphorylation of non-coordinated cyclopropenone takes place at the carbon-carbon double bond furnishing compound (IV). -(KURAMSHIN, A.
