- Fast and efficient synthesis of sulfinamides by the oxidation of sulfenamides using potassium fluoride and m-chloroperoxybenzoic acid
-
A procedure for the synthesis of N-alkyl-, N-cycloalkyl-, N,N-dialkyl-, and N-arylarenesulfinamides from the corresponding sulfenamides using KF/m-chloroperoxybenzoic acid (CPBA) in CH3CN-H2O is described. High efficiency (fast react

- One-pot synthesis of sulfonamides from methyl sulfinates using ultrasound
-
Room temperature ultrasonic irradiation of neat mixtures of methyl sulfinates and primary or secondary amines (1.5 equiv) produced sulfinamides, which on m-CPBA oxidation (in dichloromethane) were converted into the corresponding sulfonamides. The two steps can be accomplished in one pot, in good overall yields, when using secondary amines, but primary amines give better sulfonamide yields when the peracid oxidation is effected on the purified sulfinamide. This constitutes a mild, efficient, and potentially scalable route to sulfonamides, which obviates the use of water sensitive, often lachrymatory sulfonyl chlorides and large reagent excesses.

- Expedient synthesis of sulfinamides from sulfonyl chlorides
-
Sulfinamides were synthesized from sulfonyl chlorides using a procedure involving in situ reduction of sulfonyl chlorides. The reaction is broad in scope and easy to perform.
