HYDROBORATION D'AMINES INSATUREES. V. NOUVELLE VOIE D'ACCES AUX AMIOALKYLIDENECYCLOALKANES
Hydroboration of various 1-bromopropargylamines by borinane and 3,6-dimethylborepane has led to α-bromovinylboranes.Treatment of these compounds with iodine in basic media, only gives aminoalkylidenecycloalkanes with excellent yields.
