Phenylmagnesium bromide and methylmagnesium bromide in tetrahydrofuran undergo a regioselective addition to the cyano group of the two title compounds. Phenyllithium and methyllithium add selectively to the azomethine portion of 2-[(benzylidene)amino]benzonitrile, but to the cyano group of 2-[(diphenylmethylene)amino]benzonitrile. These addition reactions are utilized in the synthesis of quinazoline
四氢呋喃中的苯基溴化镁和甲基溴化镁在两个标题化合物的氰基上进行区域选择性加成。苯基锂和甲基锂选择性地加到2-[((亚苄基)氨基]苄腈的偶氮甲碱部分,但加到2-[(二苯基亚甲基)氨基]苄腈的氰基上。这些加成反应用于合成喹唑啉衍生物。
