Reactions of Cyclic Peroxides with Aldehydes and Ketones catalysed by Trimethylsilyl Trifluoromethanesulphonate. An Efficient Synthesis of 1,2,4-Trioxanes

Jefford, Charles W.,Boukouvalas, John,Kohmoto, Shigeo

, p. 523 - 524 (2007/10/02)

Trimethylsilyl trifluoromethanesulphonate is found to be an efficient catalyst for the reaction of 1,4-endoperoxides and 1,2-dioxetanes with aldehydes and ketones to give 1,2,4-trioxanes in high yields.
