Exposure of N-heterocycles and aliphatic trialkylamines to trifluoromethanesulfonylimino-lambda(3)-bromane at room temperature results in direct transfer of the sulfonylimino group to the nitrogen atoms and affords a variety of iminoammonium ylides under transition-metal-free conditions. The imino-lambda(3)-bromane probably serves as an active nitrenoid species without any activation and produces the ammonium ylides via a bimolecular nucleophilic substitution process.
在室温下，将氮杂环和脂肪族三烷基胺暴露于三氟甲磺酰亚氨基-λ(3)-溴烷，会导致磺酰亚氨基直接转移至氮原子上，并在无过渡金属的条件下生成多种亚氨基铵叶立德。亚氨基-λ(3)-溴烷可能作为一种无需任何活化的活性氮烯类物种，并通过双分子亲核取代过程生成铵叶立德。
