The rate constants, k, for the decomposition of ammonium trichloroacetate in acetonitrile were determined at 298 K BHCCl3COO [graphic omitted] CHCl3+ CO2+ B where B is an N-base. The first-order decarboxylation of trichloroacetic acid in the presence of N-bases is strongly dependent upon proton transfer in ([graphic omitted]) complexes.
三氯乙酸铵在乙腈中的分解速率常数k在298 K BHCCl 3 COO CHCl 3 + CO 2 + B处测定,其中B为N基。在N碱存在下三氯乙酸的一级脱羧作用在很大程度上取决于质子在(复合物)中的质子转移。
