Halo-2-X-cycloalkanes

Addition of aryl tellurium trihalides to cyclohexene produces rra 5-l-aryldihalotelluro-2-halocyclohexanes when the reactions are carried out in chloroform, and trans- -aryldihalotelluro-2-methoxycyclohexanes when methanol is used as the reaction medium. Treatment of the 2-chlorocyclohexyl 4-methoxyphenyl tellurium dichloride with ter/.-butyl hydroperoxide in acetic acid yielded trani-l,2-dichlorocyclohexane and aryl chloride. Bis[4-methoxyphenyl] tellurium dichloride did not yield any aryl chloride under these conditions. Pyrolysis of tra .s-2-methoxycyclohexyl phenyl tellurium dibromide afforded trans-1 -bromo-2-methoxycyclohexane.  

Irgolic Organo Tellurium Compounds with 2 Tc —C Bonds or 1 Te = C Bond 

Upon pyrolyses, bis[2-chloroalkyl] tellurium dichlorides, obtained from tellurium tetrachloride and propene or 1-butene, yielded v/c.-dichloroalkanes among other products
