1-Substituted 3,3-dimethylbenzo[d]-1,3-azasilolines (III) were synthesized by intramolecular cyclization of the corresponding (3-chlorophenyl)(N-substituted aminomethyl)dimethylsilanes (II) by the use of phenyllithium. Reaction of III with benzyne generated from o-fluorobromobenzene and n-butyllithium gave 1-phenyl-2-substituted-3,3-dimethylbenzo[d]-1,3-azasilolines (VIII).
通过使用苯基锂将相应的(3-氯苯基)(N-取代的氨基甲基)二甲基硅烷(II)进行分子内环化反应,合成了1-取代的3,3-二甲基苯并[ d ] -1,3-氮杂三环(III)。III与由邻氟溴苯和正丁基锂生成的苯并炔反应,得到1-苯基-2-取代的3,3-二甲基苯并[ d ] -1,3-氮杂双环(VIII)。
