The germyl- and silylphosphines R3MPEt2 (M = Ge, Si) condense by a dipolar 1,2-addition to one of the carbonyl groups of the α-diketones and lead to phosphorus ketoalcoxygermanes or -silanes. The action of germyl- and silyldiphosphines R2M(PEt2)2 on the diacetyl compound leads to acyclic derivatives from 1,1- and 1,2-addition to the carbonyl group as well as to the cycloaddition derivatives: the 2-germa
