摘要

OPPI BRIEFS Volume 24, No. 2, 1992 mixture washes away dimethyl sulfoxide and triethylamine hydrobromide or hydroiodide formed in the reaction, affording essentially pure products 2. Unsymmetrical dialkyl Meldnun's acids are also obtained in very high yields when monosubstituted Meldrum's acids used as starting materials. To extend the scope of the reaction, two bishalides,% a'-dibromo-o-xylene (3) and 2, 2'-bis (bromomethy1)-1, l'- ...
