kcal/mol. For most of these hydroxylic acids, the BDEs of the O−H bonds estimated by eq 1 are within ±2 kcal/mol of the literature values in nonpolar solvents or in the gas phase. There is no reason to believe, therefore, that these BDEs are “seriously in error because of failure to correct for solvent effects” as has been claimed on the basis that BDEs in highly polar solvents estimated for the O−H bond
DMSO 溶液中 O-H 键的均裂键解离能 (BDE),用于 (a) 苯酚及其许多衍生物、(b) 三种肟、(c) 三种醇、(d) 三种羟胺和 (e ) 两种异羟肟酸已通过等式 1 估算:BDEHA = 1.37pKHA + 23.1Eox(A-) + 73.3 kcal/mol。对于大多数这些羟基酸,在非极性溶剂或气相中,由方程 1 估计的 OH 键的 BDE 与文献值的 ±2 kcal/mol 范围内。因此,没有理由相信这些 BDE 是“由于未能纠正溶剂效应而出现严重错误”,因为高极性溶剂中的 BDE 是根据光声法估计苯酚中的 O-H 键所声称的。量热法必须如此校正。
