A manganese pincer complex catalyzes an unprecedented acceptorless dehydrogenative coupling of alkyl sulfones with alcohols to provide highly functionalized vinyl sulfones in good yields. Several functional groups including bromides and iodides are tolerated under the reaction conditions. This environmentally benign reaction produces dihydrogen and water as byproducts.
