Functionalised indolines have been prepared by treating tetrathiafulva
lene (TTF) with 2-(N-acyl-N-allylamino)benzenediazonium tetrafluorobor
ates. N-Benzoyl-protected substrates afford complex reaction mixtures
due to competing radical cyclisation onto the benzoyl group, Acetamide
s react more efficiently affording good yields of product alcohols whe
n the reactions are carried out in moist acetone.
