GHORBANI-VAGHEI, Ramin et al. Highly efficient formylation of alcohols, thiols and aniline derivatives by a heterogeneous (HCOOH/SiO2) system under microwave irradiation and solvent-free conditions. S.Afr.j.chem. (Online) [online]. 2009, vol.62, pp.39-43. ISSN 1996-840X.
A simple, rapid and efficient microwave-assisted procedure for the formylation of aniline derivatives and alcohols, using a heterogeneous (HCOOH/SiO2) system under solvent-free conditions is reported. The method is applied to a set of amines, alcohols and thiols and short reaction times (<10 min) with high yields are reported. This protocol introduces a practical and viable green technology of solvent-free and catalyst-free reactions.
