The reaction between bis(2-benzothiazolyl) ketone (1) and a series of ring-substituted phenyl Grignard reagents gives, in considerable amount, the unexpected O-alkylation product derived from the attack of the Grignard reagent to the carbonyloxygenatom, thus extending the range of rarely reported cases in which O-alkylation can occur. The expected classic 1,2-addition product and that derived from
