The Action of the Grignard Reagent on ο-Phthalic Esters

Le résumé fourni par la source

1. In spite of the great analogy existing between o-phthalic acid and succinic acid, the action of the Grignard reagent upon o-phthalic esters differs from that upon succinic esters in producing derivatives of phthalide, instead of producing glycols. 2. More frequently, the reaction between the Grignard reagent and o-phthalic esters goes even one step further, with production of the derivatives of phthalane. 1:1-Dimethyl-3-methylene-phthalane, 1:1-diphenyl-3-phenylene-phthalane and 1:1-dibenzyl-3-benzal-phthalane have thus been obtained and described. 3. Various space formulae proposed for benzene are discussed from the point of view of the experimental results obtained in this investigation, and it is shown that GRAEBE'S model, which represents KEKULE'S well known formula in space, accounts for the facts in the most satisfactory manner. In conclusion, I desire to express my best thanks to Professor MATSUBARA for his kind guidance and suggestions.
