A novel Cu-catalyzed intermolecular chemoselectivity dithiocyanation of styrenes with ammonium thiocyanate has been developed under mild conditions. This reaction exhibits a wide range of functional-group tolerance in styrenes to afford various dithiocyanates. The reaction mechanism was primarily investigated and a radical process was proposed.

The one-pot anodic thiocyanation and isothiocyanation of alkenes in both acidic two-phase (water-dichloromethane) and homogeneous one-phase (water-acetonitrile) media has been studied. Optimisation experiments on tetramethylethylene as a model alkene invo

supporting information, p. 4031 - 4034 (2015/06/02)
A facile and efficient protocol of oxythiocyanation of styrenes with ammonium thiocyanate has been developed. The reaction proceeded at room temperature using oxygen as sole oxidant to afford the α-oxothiocyanates via radical pathway in moderate to good yields. This method is straightforward, green and cost-effective, requires no catalyst and additives.

Radical additions to olefins in the presence of iodobenzenediacetate: An easy route to alkyl dithiocyanates
De Mico, Antonella,Margarita, Roberto,Mariani, Andrea,Piancatelli, Giovanni
, p. 1889 - 1892 (2007/10/03)
We describe a new application of iodobenzenediacetate (IBDA), which is able to oxidize thiocyanate anion to the corresponding radical. Subsequent addition to nucleophilic olefins leads to dithiocyanate derivatives. The radical addition to olefins is more effective when performing the thiocyanation reaction in presence of Mg(ClO4)2 or TEMPO.

, p. 1814 - 1822 (2007/10/02)
The rate of the doping addition in the reactions of 2,4-dinitrophenylsulfenyl chloride with cyclohexene an methylenecyclobutane and of dithiocyanogen with cyclohexene and substituted styrenes in the presence of lithium perchlorate is described by the normal salt effect equation.On the other hand, the rate of formation of the doping products may exceed or lag behind the increase in the total reaction rate.These results were interpreted in the framework of an ion-pair mechanism.

, p. 1577 - 1581 (2007/10/02)
A number of epoxides smoothly react with TPPT under mild conditions to give α-thiocyanatovinyl ketones, vic-dithiocyanates, or vic-thiocyanatohydrins, depending on the structures of the epoxides used.The reactions proceed site- and stereo-specifically, to give α-thiocyanatovinyl ketones from αβ-epoxyketones, threo-dithiocyanate from trans-epoxide, erythro-dithiocyanate from cis-epoxide, and vic-thiocyanatohydrins from 1,1-disubstituted or fused epoxides, respectively.A possible mechanism for these reactions is put forward.
