THE REACTION OF 2-(1,3-BUTADIENYL)MAGNESIUM CHLORIDE

Abstract

Abstract The reaction of 2-(1,3-butadienyl)magnesium chloride (1) with aldehydes and ketones afforded a mixture of 1,3-dienyl alcohol (3) and 1,2-dienyl alcohol (4). The selective formation of another 1,3-dienyl alcohol (6) was observed when the Grignard reagent (1) was treated with epoxides. The latter reaction was applied to the synthesis of the sex attractant of a bark beetle.
