A rapid and facile method provides a general route to sulfonyl bromides/chlorides by the oxidation of thiols using NXS – ROH (X = Br,Cl, R = i Pr) as an oxyhalogenation reagent. Control experiments suggest that the alcohol component is the source o

We report an efficient method for the regiodivergent synthesis of halogenated resorcinol derivatives using readily available vinylogous esters and sulfonyl halide halogen donors. Either the 4- or 6-haloresorcinol isomer is accessible from a common pr
