On the basis of experimental results, Arnold (,Isopropenyl acetate acts as an acetyl transfer reagent in vinylogous additive Pummerer reactions, providing an efficient means for the conversion of vinyl sulfoxides to α-acyl sulfides (,Interestingly, carboxylic acids can be converted into the corresponding methylthiomethyl derivatives (.α-Fluoro sulfides are conveniently prepared by the Pummerer-type reaction of sulfoxides with (diethylamino)sulfur trifluoride (DAST).Acylation of thiols with ketenes (equation,Metal thiolates or benzenethiols in the presence of triethylamine also react very smoothly with diketene to yield,Acylation of a simple thiol with an alkyl carboxylate is not a very suitable method for preparation of.Phenyl carboxylates are reactive enough to form thiocarboxylic esters directly with thiols or thiolate anions.The highly activated 4-acyloxypyridines react with thiols under particularly mild conditions (room temperature, no acids or bases) to form.As expected, formation of five- and six-membered thiolactones is a favored process.

The difference between the carbonyl carbon–nitrogen bond of an amide and the carbon–nitrogen bond of an amine is larger than 7 pm.These workers showed that if water is removed during the reaction, Reaction 7-9 occurred in approximately the ratio 2:1:1 in an uncatalyzed system. 1 Structures Expand this section. 2 Names and Identifiers Expand this section. Reaction with acid chlorides readily converts amines into amides.Explain why the carbonyl carbon–oxygen single bond of esters is about 7 pm shorter than the carbon–oxygen bond of an ether.
