Cu-doped zeolitic imidazolate framework catalysed highly selective conversion of alkynes to β -keto and vinyl sulfones using sodium sulfinates

Abstract: Cu 2 +-doped zeolitic imidazolate framework-8 (ZIF-8)-catalyzed one-pot procedure to synthesize β -keto and vinyl sulfones by the direct oxysulfonylation and hydrosulfonylation of alkynes via radical reaction under mild conditions has been described. The advantages of this protocol included broad substrate scope and excellent β -keto and E-stereoselectivity. The Cu/ZIF-8 catalyst not only exhibited excellent performance but also had a great stability in the reaction, successfully allowing its reuse up to five cycles. This efficient Cu/ZIF-8 heterogeneous catalyst is explored for the first time to generate β -keto and vinyl sulfones.

Silver(I)-mediated reaction of trimethylsilylated arylacetylenes with sulfonyl chlorides: Unexpected formation of vinyl sulfones

A novel reaction of trimethylsilylated arylacetylenes with sulfonyl chlorides was performed in the presence of silver nitrate or triflate. Conjugated vinyl sulfones as dramatic products were obtained in moderate yields and with Z-selectivity. A free radical mechanism has been proposed to account for the formation of the products.
