29 - 134Synthesis of N-(Arylprop-2-en-1-yl)benzotriazoles by the HeckReaction. — Heck reaction of aryl halides (I) and (VI) with 1-prop-2-en-1-ylbenzotriazoles (II) allows the synthesis of the correspondingalkenylbenzotriazoles which are useful synthons for the preparation of dienes,β,γ-unsaturated ketones, alcohols and amines. The N-vinylbenzotriazole (IV)reacts under similar conditions in shorter reaction times. — (KATRITZKY,ALAN R.; FERWANAH, ABD EL-RAHMAN S.; DENISENKO, SERGEY N.;Heterocycles 50 (1999) 2, 767-777; Dep.
