【 摘 要 】

The rate constants for the reactions of diazodiphenylmethane (DDM) with2-substituted nicotinic acids in nine aprotic solvents at 30°C weredetermined. The obtained second order rate constants in aprotic solvents,were correlated using the Kamlet-Taft solvatochromic equation in the completeform: log k = log k0 + sπ
