摘　　要：本文通过一系列配体取代反应证实氨基乙醇、氨基酸、2-(α-羟基苄基)苯骈咪唑(HBB)、8-羟基喹啉(8-HQ)等N,O双齿配体与二芳基硼的螯合能力存在下列强弱顺序: 8-HQ>HBB>NH_2CH_2CH_2OH>RCH(NH_2)COOH相应螯合物的稳定性也依此序递降,有关四配位二芳基硼螯合物可按这一规律直接进行转化。Through a series of ligand substitution reactions, the chelating abilities of ethanolamine, amino acids, 2-(α-hydroxybenzyl)bcnzimidazoIe(HBB), 8-hydroxy quinoline(8-HQ) to diarylboron moiety were observed in a decreasing: 8-HQ > HBB > NH2CH2CH2OH > RCH(NH2)COOH The corresponding stabilities of diarylboron chelates therefore decrease in the same order and the chelate with a weak ligand could be converted to a chelate with a strong ligand according to this order.
