Preview

Highly regioselective tungsten (W)-catalyzed allylic sulfonylation of allylic carbonates with readily available sulfonyl hydrazides has been developed. Under tungsten catalysis, a variety of allylic sulfones can be delivered with the help of 4,4'-di-tert-butyl-2,2'bipyridine in moderate to good yields with excellent b/l regioselectivities. This approach features mild conditions, broad substrate scope, where aryl-and alkyl-substituted allylic carbonates and sulfonyl hydrazides are suitable substrates. This noble-metal-free catalyst system exhibits high reactivity and regioselectivity for the construction of C-S bond.
