The protocol promotes intermolecular coupling of alkenes with readily available disulfides under mild conditions, providing access to vicinal dithioethers with broad substrate scope and excellent functional-group tolerance. More than 30 combinations of alkenes and disulfides demonstrate the generality and practicality of the transformation. Mechanistically, the highly electrophilic silylium ion is proposed to activate the disulfide in the form of a sulfonium ion, thereby turning it into a sulfenium-ion carrier. Both an example of an initially formed sulfonium ion [Et3Si(EtSSEt)][HCB11H5Br6] and a subsequently generated electrophile [MeS(MeSSMe)][HCB11H5Br6] were isolated and characterized by X-ray diffraction. Transfer of the sulfenium-ion electrophile from these cations to the C\u2013C double bond, followed by attack of another disulfide molecule as a sulfur nucleophile, allows for the formation of two C\u2013S bonds without the need for a transition-metal catalyst or an external oxidant.<\/jats:p>","DOI":"10.1021\/acs.joc.6c01661","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T18:01:32Z","timestamp":1786125692000},"page":"11559-11564","source":"Crossref","is-referenced-by-count":0,"title":["Silylium-Ion-Initiated\nDisulfidation of Unactivated\nAlkenes with Disulfides: Methodology and Isolation of the Sulfenium-Ion\nCarriers"],"prefix":"10.1021","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8172-4673","authenticated-orcid":true,"given":"Biping","family":"Xu","sequence":"first","affiliation":[{"name":"Technische Universita\u0308t Berlin , , Stra\u00dfe des 17.
