The stereochemistry of organometallic compounds. XLIII* rhodium-catalysed reactions of 2-(alkenyloxy)benzylamines and 2-(N-allyl-N-benzylamino)benzylamine

Article abstract of DOI:10.1071/CH9960219

Reactions of 2-(allyloxy)benzylamines with H₂/CO in the presence of rhodium catalysts give 1,3-benzoxazines, and 2-(N-allyl-N-benzylamino)benzylamine gives a quinazoline. These reactions have been shown to involve allylic cleavage followed by regioselective carbonylation at the internal carbon atom as demonstrated by crossover experiments. Reactions of longer chain (alkenyloxy)benzylamines under similar conditions give polymeric material.
