The classical Reformatsky reaction proceeds normally when a-bromolactones replace a- bromo esters. A variety of aromatic carbonyl compounds and one alicyclic ketone were condensed with a-bromo-ybutyrolactone to yield both hydroxy and unsaturated addition products. 4, 4'-Dimethoxybenzophenone and a-bromo-r-butyrolactone reacted normally in benzene-ether solvents, but, when tetrahydrofuran was used as a solvent, a major product ...
