The reaction of 2-vinyloxyethyl isothiocyanate with aliphatic (saturated, unsaturated) and aromatic carboxylic acids leads quantitatively to partial acylals with isocyanate groups.The process takes place at room temperature or with moderate heating and, as a rule, without solvents in the presence of catalytic amounts of heptafluorobutyric acids.From the products of the reaction with benzoic and saturated aliphatic acids 1,3-oxazolidine-2-thione and its polymer were isolated in small amounts (5-7percent) in addition to the respective acylals.

The reaction of the simplest alcohols with 2-vinyloxyethyl isothiocyanate under electrophilic conditions leads to previously unknown acetals containing an isothiocyanate group.Under the reaction conditions (0.2-1.3 wtpercent of perfluorobutyric acid, 40-80, 0.6-3 h) 1,3-oxazolidine-2-thione is formed in addition to the corresponding acetals.The conditions were found which make it possible to direct the reaction toward the preferential formation of either 1,3-oxazolidine-2-thione or the 2-isothiocyanatoethyl acetals of acetaldehyde.
