reaction center (carbon atom in the CH2-group) for the latter were obtained in the quantum-chemical calculations by RHF/6-31G(d) method. This explains the possibility and the ease of dehydrogenation of N-benzyl-4-[9-(thio)xanthenyl]aniline with imines in trifluoroacetic acid due to effect of the substituents. The calculated data suggest the same possibility for N-benzyl-4-(5-dibenzosuberenyl)aniline: it
N-苄基-4- [9-(硫代)-黄嘌呤]苯胺,N-苄基-4-(5-二苯并亚戊烯基)苯胺分子的最高占据分子轨道的能量和它们的两性离子和电子密度增加通过RHF / 6-31G(d)方法进行量子化学计算,获得了后者的反应中心(CH 2-基团中的碳原子)。这解释了由于取代基的作用,N-苄基-4- [9-(硫代)黄蒽基]苯胺与亚胺在三氟乙酸中脱氢的可能性和容易性。计算数据表明,N-苄基-4-(5-二苯并亚戊烯基)苯胺具有相同的可能性:在N的合成中已脱氢-苄基苯胺和二苯并戊烯醇在乙酸中。
