A series of fluoroalkylated 1,2,3-triazoles have been synthetised in significant yields through unexpected intramolecular cyclisations of vinyl azides bearing electron-withdrawing groups. The mechanism proposed in this study implies the participation of a catalytic amount of azide ions in the cyclisations of the vinyl azides to triazoles. The study includes the alkylation of these compounds with various
通过带有吸电子基团的乙烯基叠氮化物的出人意料的分子内环化,已经以显着的产率合成了一系列氟烷基化的 1,2,3-三唑。本研究中提出的机制意味着催化量的叠氮离子参与乙烯基叠氮化物环化为三唑。该研究包括用各种烷化剂对这些化合物进行烷基化,并评估离子衍生物的表面活性。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2008 年)
