First allylboration of organic compounds with the NN double bond. Synthesis of N-allylpyrazolidines and allyl-1,2-diphenylhydrazine

Allylic boranes are chemist’s best friends: Reactivity, applications, new opportunities

“…Two examples of monoallylboration are presented in Scheme 13: synthesis of butenyl thiols [24] and N-allylation of pyrazoline derivative 33 [25].…”
