The Liquid Crystalline State as a Criterion in Determination of Structure. I. Crystalline Liquid Benzoic Acid and Thiobenzoic Acid Pyrimidinyl-(2)-estersThe acylation of subst. 1H-pyrimidinethiones-(2) 3 and 4, as well as of subst. 1H-pyrimidinones-(2) 7 is investigated. Due to the tautomeric equilibrium in the starting materials the reactions may lead to N-, S-, or O-esters. The liquid crystalline properties of the reaction products formed prove that S- and O-acylated esters 5, 6, and 8 had been formed only. Spectroscopic data confirm this.
