520 3 |a The reaction of tellurium tetrachloride with propargyl bromide in boiling benzene regio- and stereoselectively afforded bis[(Z)-3-bromo-2-chloroprop-1-en-1-yl]tellurium dichloride which was readily reduced to bis[(Z)-3-bromo-2-chloroprop-1-en-1-yl] telluride. Propargyl chloride reacted with tellurium tetrachloride preliminarily stored for several months (and containing decomposition products) to give a mixture of bis[(Z)-2,3-dichloroprop-1-en-1-yl]tellurium dichloride and regioisomeric [(Z)-1,3-dichloroprop-1-en-2-yl]- [(Z)-2,3-dichloroprop-1-en-1-yl]tellurium dichloride at a ratio of 3: 2, whereas the latter was formed as the sole product in the reaction with freshly prepared tellurium tetrachloride. Reduction of the regioisomer mixture produced the corresponding tellurides. The structure of the isolated compounds was confirmed by 1H, 13C, and 125Te NMR spectra.
