Ring cleavage of a variety of N-substituted aziridines has been studied with hydroxyl compounds (primary, secondary, allylic and tertiary). It was observed that the cleavage reaction was very facile in the presence of BF3·OEt2 and Sn(OTf)2. Whereas the aziridine opening reaction was facile with primary and secondary alcohols, hindered alcohols took longer (2 days). However, with the help of microwave
已经用羟基化合物(伯,仲,烯丙基和叔)研究了各种N-取代的氮丙啶的环裂解。观察到在存在BF 3 ·OEt 2和Sn(OTf)2的情况下,裂解反应非常容易。氮丙啶开环反应易于使用伯醇和仲醇进行,而受阻醇则需要更长的时间(2天)。但是,借助微波辐射,可以在很短的时间内(15分钟)完成与受阻醇的裂解反应。苯酚只能在微波辐射下裂解氮丙啶。
