Allylic rearrangements during the rhodium-catalysed reactions of 2-allyloxybenzylamines and 2-(N-allyl-N-benzylamino)benzylamine
Abstract
Reactions of 2-allyloxybenzylamines with H2/CO in the presence of rhodium catalysts give 1,3-benzoxazines via a reaction which involves allylic cleavage and carbonylation as demonstrated by crossover experiments.
