title: Iron/Copper co-catalyzed synthesis of vinyl sulfones from sulfonyl hydrazides and alkyne derivatives.
abstract: A new approach to the selective synthesis of (E)-vinyl sulfones has been developed via a Fe/Cu co-catalyzed sulfonylation of arylpropiolic acid or phenylacetylene with sulfonyl hydrazides. A variety of vinyl sulfones have been obtained in moderate to good yields, comparable to the best results reported so far. The inexpensive Fe/Cu co-catalyzed method features a simple experimental procedure and good tolerance of substrate.
