Oxidation of the adducts formed from tricarbonyl(vinylketene)iron(0) complexes and alkynes by iron(III) chloride in methanol/water leads to the replacement of the tricarbonyliron(0) unit with an oxygen atom derived from the water.This pathway to furan-3(2H)-ones requires the presence of an electron-withdrawing substituent on carbon-2 of the vinylketene-alkyne adduct.Data used to assign the structures of some of the vinylketene-alkyne adducts used in this study included an X-ray crystal structure analysis of the unusual lactone complex 5c.

Bicyclo[1.1.1]pentane (BCP) is widely applied as the bioisostere for aryl, internal alkynes, andtert-butyl groups in medicinal chemistry. We herein disclose an efficient and practical preparation of sulfonyl alkynyl/allyl/cyano-substituted BCP derivatives

Visible-light-promoted intermolecular radical cyclization of disulfides and alkynes has been developed. Benzothiophenes bearing ester, ketone, aldehyde and aryl substituents were synthesized in good yields. The reaction was carried out in the absence of t
