A direct oxidative esterification of aldehydes with alcohols mediated by photochemical C-H bromination.

The photochemical direct esterification of aldehydes with alcohols via in situ -generated acyl-bromides presented in this report is an attractive complementary addition to hitherto reported methods, as these are usually carried out in a two-step, one-pot procedure in order to avoid side reactions such as the oxidation of alcohols by halogen sources.
