N2 - Unsymmetrical dialkyltellurides of type RTeR′ suitable for use as precursors in the metalorganic vapour phase epitaxy (MOVPE) of cadmium mercury telluride (CMT) can be prepared by an alkyl exchange process. For certain organotellurium compounds, reaction of R2Te (R = alkyl, allyl) with R′2Te2 (R′ = alkyl) produces an equilibrium mixture containing RTeR′ and RTe2R′. Suitable selection of R and R′ allows good yields of RTeR′ to be prepared in high purity. ESR studies show that free radicals are formed on thermal or photochemical decomposition of R2Te and that the stability of (allyl)TeMe is very similar to that of (allyl)2Te but quite different from that of Me2Te.
