DOI: 10.1021/acs.orglett.2c02346
Abstract: A novel visible-light-promoted coupling of diazoketones with sulfoxonium ylides, employing a violet light-emitting diode, is described under both batch and continuous flow conditions. This transformation permits the direct synthesis of synthetically useful 1,3-dicarbonyl sulfoxonium ylides… read more here.

DOI: 10.1021/acs.orglett.3c00143
Abstract: The visible-light-induced photoredox carbon radical formation from aqueous sulfoxonium ylides has been demonstrated for the first time. While direct reduction of sulfoxonium ylides by H2O efficiently generates the corresponding hydrocarbon compounds, the use of additional… read more here.

DOI: 10.1021/acs.orglett.8b03744
Abstract: The lack of general access to bis-substituted sulfoxonium ylides is addressed by developing a palladium-catalyzed C-H cross-coupling of α-ester sulfoxonium ylides with (hetero)aryl iodides, bromides, and triflates. Three different catalysts have been evaluated. This method… read more here.

DOI: 10.1039/d1cc02576g
Abstract: Previous transition metal-catalyzed synthesis processes of δ-diketones are plagued by the high cost of the rhodium catalyst and harsh reaction conditions. Herein a low-cost, room temperature ruthenium catalytic method is developed based on the coupling… read more here.

DOI: 10.1039/d1qo00550b
Abstract: A novel radical cross-coupling/cyclization of 2-(pyridin-2-yl)acetate derivatives and sulfoxonium ylides is developed, which provides a straightforward access to structurally diverse methylthio-substituted indolizine. A series of 1,2,3-trisubstituted indolizines are readily synthesized in modest yields. In this… read more here.

DOI: 10.1055/s-0036-1588814
Abstract: Cobalt demonstrates a remarkable ability to catalytically divert the course of epoxide to oxetane ring expansion via reaction with a sulfoxonium ylide. An expanded survey of transition-metal catalysts has confirmed that cobalt salts uniquely instead… read more here.
