Examples describe the preparation of S - acetyl mercaptoacetamide, S - acetyl - N - methyl-mercaptoacetamide, S-acetyl-mercaptopropionamide and S - succinyl - mercaptoacetamide by reacting the appropriate mercaptoalkylamide with the appropriate acid anhydride or with acetyl chloride. The novel ...
an acid chloride, and the molar ratio of the halogen atom in the acid halide to the cyano group in the cyano-tin compound is 2:1-1:2. The tin halide produced by the reaction is converted to the cyano-tin compound by reacting with an alkali cyanide, etc., and reused. The reaction ...

The R′ group becomes the first word, and the second word is formed by changing the parent acid -ic to -ate. For example, CH3CH2CH2CO2CH3 is methyl butanoate. Amides (RCO–NH2) are named by replacing the name of the corresponding acid by the systematic ending -amide. As with amines,...

Is it similiar to the imidolyl chloride intermediate formation ? As it was mentioned in the Amide bond formation and peptide coupling paperwork, so maybe it forms intermediate product with amines and acyl chloride forms only in the presence of amines ?Greetings Logged wildfyr Global Moderator ...
Subsequently, anhydrous dichloromethane (25 mL) was added and the mixture was stirred at room temperature (RT) for 5 min before dropwise addition of oxalyl chloride (3.0 mmol, 3.0 eq). The reaction mixture was then stirred at reflux for 2.5–3.0 h before cooling to RT and the solvent was...
