✦ Synopsis

2-Substituted-4hydroxymethyltellurophenes and acetylenic ally1 alcohols (enynols) are products from the action of sodium telluride on acetylenic epichlorohydrins.

Variation in the degree of reduction of tellurium to telluride ion has a dramatic effect on the ratio of tellurophene to ally1 alcohol, either of which may be obtained as the major product.

Recently we reported that chloromethyloxiranes (epichlorohydrins) am easily converted to ally1 alcohols by the action of sodium telluride in aqueous base.l In the preparation of acetylenic substituted
