describes the synthesis and full characterization of a series of GaCl3 and B(C6F5)3 adducts of diazenes R1NNR2 (R1=R2=Me3Si, Ph; R1=Me3Si, R2=Ph). Trans‐PhNNPh forms a stable adduct with GaCl3, whereas no adduct, but instead a frustrated Lewis acid–base pair is formed with B(C6F5)3. The cis‐PhNNPh⋅B(C6F5)3 adduct could only be isolated when UV light was used, which triggers the isomerization from
这项工作描述了一系列的GaCl的的合成和全面表征3和B(C 6 ˚F 5)3二个氮烯的R加合物1 NN - [R 2(R 1 = R 2 =我3的Si中,Ph; R 1= Me 3 Si,R 2= Ph)。反式-Ph NN pH下形成具有的GaCl稳定加合物3,而没有加合物,而是一个沮丧
路易斯酸碱对与B(C形成6 ˚F 5)3。这顺-Ph NN 博士⋅ B(C 6 ˚F 5)3,使用UV光时加合物只能被分离,这将触发来自异构化的反式-对顺-Ph NN pH值,这提供了更多的笨重的
