Novel catalytic system consisting of a 3,3′-tetramethylene-bridged 4-methylthiazolium salt leading to the partial reduction of nitrobenzene with benzaldehyde to a nitrone
Abstract
A 3,3′-tetramethylene-bridged 4-methylthiazolium salt catalyses the reduction of nitrobenzene with benzaldehyde and triethylamine in methanol–water to give a nitrone.
