Organotin monohydrides were brought into reaction with a variety of mono- and disubstituted ethynes. The identity of the resulting products was established by means of elementary analysis, infrared absorption spectroscopy and proton magnetic resonance spectroscopy.

trans-addition products formed in the hydrostannation of ethynes has been shown to proceed under the influence of organotin radicals. Attack of such radicals on the carbon-carbon doublebond produces an ethyl radical containing two organotin groups. Elimination of one of the organotin moieties as a radical may result in the formation of the isomerized product. The course of the latter step is determined
