Abstract

The reaction of aromatic aldehyde oximes with TBSCl and imidazole in DMF generates the corresponding O-silylated derivative, which undergoes elimination, affording the nitrile with a high yield. For the fragmentation of the predominantly (E) isomer, a base-catalyzed syn elimination mechanism is proposed.
