method for the preparation of diphenylboron chelates from ammonium tetraphenylborate is described. A variety of five- or six-membered O,O-, N,O- and N,N-chelates were obtained in yields from 60 to 90 %. The isolated compounds were characterized by elemental analysis, IR spectroscopy and multinuclear magnetic resonance spectroscopy (1H, 13C, and 11B). The crystal and molecular structures of (pyridine
描述了一种从四苯基硼酸铵制备二苯基硼螯合物的简便方法。以 60% 到 90% 的产率获得了各种五元或六元 O, O-, N, O- 和 N, N- 螯合物。分离出的化合物通过元素分析、红外光谱和多核磁共振光谱(1H、13C 和 11B)进行表征。(pyridine-2-acetyloximato) diphenylboron 和 (1-phenylazo-2-naphtholato) diphenylboron 的晶体和分子结构是通过 X 射线衍射在单晶上确定的。
