Thionocarboxylic ester

Analogously to carboxylic esters, thionocarboxylic esters can be synthesized by the azolide method. An example is the synthesis of thionobenzoic acid methyl ester via a 1 -thioacyl-4-alkyl-1,2,4-triazolium tetrafluoroborate and methanol.[175]... [Pg.73]

The thioacylation of NH groups by dithiocarboxylic esters and their salts, as well as by thionocarboxylic esters, is dealt with in Section 5 of this chapter. Diphenylcyclopropenethione reacts with amines to give the cycloadducts (91), which are rearranged to the thioamides (92) when heated in benzene. Thioamides RNHC(S)CHXY are obtained from compounds with active methylene groups by reaction with A-aryldithiocarbamic acid esters, e.g. MeSC(S)NHPh, thiocarbamoyl chlorides, or C-sulphonylthioformamides,... [Pg.160]

Synthesis of Derivatives of Thionocarboxylic Acids.—Thiono-esters are obtained by the reaction of dialkoxycarbonium ions with NajS or anhydrous NaHS in acetonitrile (Scheme 6). Cyclic carbonium salts from 1,2- or 1,3-diols give monothiono-esters of these diols. The tetrahedral intermediates in this process may be alkylated to give... [Pg.189]
