CuBr2 catalyzed bromination/oxidation of isochromans to benzaldehyde derivatives
摘要:
A series of isochromans were oxidized and brominated by using 1.2 equiv of CuBr2 in CH3CN at reflux to give the corresponding bromo benzaldehydes in moderate yields. A plausible mechanism for this transformation has been suggested. (C) 2013 Elsevier Ltd. All rights reserved.
