THE REACTION OF CARBOXYLIC ACID CHLORIDES WITH O,O-DIALKYLDITHIOPHOSPHORIC ACIDS

At high temperature (130 deg C), carboxylic acid chlorides react with O,O-dialkyldithiophosphoric acids (RO)2P(=S)(SH), Ia-c to give the corresponding dithiester RC(=S)(SR) II in varying yields, while benzoyl chloride reacts with compounds Ia, b at 20 deg C to give the corresponding S-benzoyl-O,O-dialkyldithiophosphate (RO)2P(=S) IIIa, b.Mechanistic consideration on the formation of the products are discussed.Key words: Carboxylic acid chlorides; O,O-dialkyldithiophosphoric acids, and S-benzoyl-O,O-dialkyldithiophosphates.

Reactions of 1-alkynyl thiocyanates with nucleophilic reagents. Synthesis of 2,4-disubstituted 1,3-thiazoles

Reaction of 1-alkynyl thiocyanates RCC-S-CN (1) with alcohols, phenol or thiols or secondary aliphatic amines in the presence of anhydrous zinc chloride or boron trifluoride diethyl etherate gives mixtures of 2,4-disubstituted 1,3-thiazoles (2), thiocarbonyl compounds (3) (thiono esters, dithio esters or thioamides) and 2-alkylidene-1,3-dithioles (4).In all cases, the 1,3-thiazoles can be obtained in good yields if the proper reaction conditions are applied.Interaction between 1 and lithium dialkylamides LiNR'2 gives the compounds RCC-S-NR'2 (5) (attack on sulfur).With alkoxides R'O1-, the primary attack is on CN: the in termediacy alkynethiolate RCC-S1- subsequently reacts with the alkyl cyanate R'OCN to afford 1-alkynyl sulfides RCC-SR'(6)
