描述

一般說明

Calcium hypochlorite [Ca(OCl)₂] is a stable oxidizing agent used for the conversion of ethers to esters; thioethers to sulfoxides; aldehydes to acids and alkenes to chlorohydrins. It is also used in the C-C bond cleavage and chlorination reactions.

應用

Calcium hypochlorite can be used as an oxidative agent:

• In the epoxidation of various alkene derivatives.
• To synthesize α-arylamino-α′-chloropropan-2-ones from various trifluoroacetyl-protected N-(2-chloroallyl)anilines via oxidative hydrolysis.
• To convert 1^o & 2^o alcohols, α-hydroxyamides, and α-hydroxyesters to their corresponding aldehydes, ketones, α-ketoamides, and α-ketoesters in the presence of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) as a catalyst.
• To prepare dihydrotriazolediones and bis-dihydrotriazolediones by oxidation of urazoles and bis-urazoles.
