Poly(3,4-dimethyl-5-vinylthiazolium) iodide was used as a polymer precatalyst in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and phenazine for the oxidative esterification of aldehydes with alcohols. Selective functionalization of OH groups was achieved in the presence of NH2 groups. The poly(thiazolium) iodide/DBU/phenazine system exhibited excellent catalytic activity and could be reused five times without loss of activity.

experimental part, p. 872 - 875 (2012/07/03)
A simple procedure affording benzoates through a NHC-catalyzed aerobic oxidative esterification of aldehydes with organoboronic acids has been disclosed. This process allows access to a wide variety of aromatic esters in good to excellent yields under simple, efficient, and sustainable reaction conditions (see scheme).
