Reduction of nitrosobenzene by 2-(α-hydroxyethyl)-3,4-dimethylthiazolium Salts
Abstract
Nitrosobenzene in a basic medium is reduced by 2-(α-hydroxyethyl)- or 2-(α-hydroxybenzyl)-3,4-dimethylthiazolium trifluoromethanesulfonate to yield the intermediate hydroxylamine and 2-acyl-3,4-dimethylthiazolium trifluoromethanesulfonate, with acylation of the former by the latter giving the final products.
