With phthalide two equivalents of Grignardreagent react rapidly in a reaction which could not be controlled to give stepwise addition. In contrast, 3,3- and 4,7-disubstituted phthalides react with only one equivalent of organometallic reagent. The primary addition product formed from one equivalent each of phthalide and Grignardreagent exists in a ring-chain tautomerism whose position is controlled
