Abstract

The CsF/18-crown-6 mediated reactions of disubstituted acetylenes Me3SiC=CMMe3 (M = C, Si, Ge, Sn) with carbonyl compounds in benzene were studied. In all cases the interaction proceeds with cleavage of the SI-C,, bond and can be considered as the addition of ethynylsilane to the carbonyl C=O bond. The formation of bissiloxy derivatives was detected for acetylenes with M=Si and Sn. The cleavage of the Ge-C-sp does not occur under the conditions used. Transmetallation of 1-trimethylsilyl-2-trimethylstannylacetylene was observed to give a mixture of symmetrical bissilyl- and bisstannylacetylenes with the following bis(trimethylsilyl)acetylene addition to the carbonyl compound, the bisstannyl analogue being inactive in CsF/18-crown-6 mediatedconditions. These processes open a simple way for the synthesis of new ethynyl-substituted derivatives of germanium and tin.
