A new metal-catalysed route to 4,5-dihydro-3H-1-benzazepines
Abstract
A new, short, high-yielding route to 4,5-dihydro-3H-1-benzazepines has been developed based on the rhodium-catalysed hydroformylation of readily available ortho-propenylbenzeneamines; a comparison with the hydroformylation of the corresponding ortho-propenylphenols is made.
