This article focuses on the dehydration of α‐hydroxy‐tetrazoles, leading to tetraazafulvenes and then to vinylic carbenes that rearrange into ethynyl moieties through the Fritsch–Buttenberg–Wiechell rearrangement. Each step of this sequence was scrutinized, either by examination of the substrate and/or dehydrating agent scope, or through AM1 calculations, in order to understand the limiting step of
本文着重于α-羟基四唑的脱水,导致四氮杂富烯,然后再通过Fritsch–Buttenberg–Wiechell重排而重排成乙炔基的乙烯基卡宾。通过检查底物和/或脱水剂的范围,或通过AM1计算,仔细检查该序列的每个步骤,以了解该方法的限制步骤。这种低估的转化似乎是用于将醛转化为炔烃的现有方法的可行替代方案。
