- ANOMALOUS ADDITION OF TELLURIUM TETRACHLORIDE TO ALLYLIC ESTERS. SHORT SYNTHESIS OF TRANS-(2S,3S)-2,3-EPOXYBUTANE.
-
The addition of tellurium to various allylic esters, alcohols, ethers, amides, and imino esters was studied. Allylic esters did not produce normal 1,2-chlorotelluration products, but the addition occurred 1,3 and was accompanied by a 1,2-migration of the acyloxy group. The examples include esters of allyl, alpha -methylallyl, alpha alpha -dimethylallyl, alpha -ethylallyl, methallyl, and (E)-crotyl alcohol, usually with benzoic acid but also with acetic, cinnamic, and crotonic acids.
