(Fluorosilyl)hydrazones are obtained from the reaction of lithiated hydrazones with fluorosilanes. On subsequent reaction with tert-butyllithium, cyclization takes place, to give 1,2-diaza-3-sila-5-cyclopentenes; this cyclization is favoured by the nitrogen-substituent of the hydrazone. The CH2 group of the heterocyclic compounds is a nucleophilic centre, at which further substitutions are possible
(氟硅烷基)hydr可从锂化与氟硅烷的反应中获得。随后与叔丁基锂反应,发生环化反应,得到1,2-二氮杂-3-sila-5-环戊烯; 的氮取代基有利于这种环化。杂环化合物的CH 2基团是亲核中心,在该中心可以进一步取代。报告了质谱和1 H-,19 F-和2 9 Si-NMR光谱。
