An interrupted Schmidt rearrangement/Hosomi-Sakurai reaction of N-tosyl and S-substituted vinyl azides is reported. With BF3·Et2O as a Lewis acid promoter, the denitrogenative fragmentation of vinyl azides facilitates the generation of the N/S-stabilized carbocations, which further undergo nucleophilic addition by allyl/propargylsilanes for C-C bond formation. As a result, a variety of homoallylic/allenylic amines can be afforded in good yields under mild reaction conditions with well-defined functional-group tolerance.

A fluorous Grubbs-Hoveyda metathesis catalyst supported on Teflon powder, that readily moves between the solid phase (Teflon) and the liquid phase (DMF) was prepared. By modulating the hydrophobicity of the reaction medium at the end of the reaction, the supported catalyst could be recovered by simple filtration even though the catalyst existed in a homogeneous state during the reaction. In RCM reactions, the catalyst could be reused up to three times with only a slight loss in reactivity with each subsequent cycle.

Magnetically recyclable Hoveyda-Grubbs catalyst can be readily assembled using magnetic nanoparticles as support, and this catalyst combines convenient recyclability and excellent activity on ring-closing metathesis (RCM) reactions.
Cycloisomerization promoted by the combination of a ruthenium-carbene catalyst and trimethylsilyl vinyl ether, and its application in the synthesis of heterocyclic compounds: 3-Methylene-2,3-dihydroindoles and 3-methylene-2,3- dihydrobenzofurans

Substituted N and O heterocycles have been synthesized by the cycloisomerization of dienes using a ruthenium-carbene catalyst. The products obtained with and without trimethylsilyl vinyl ether differ (see scheme, Cy = cyclohexyl, Mes = 2,4,6-trimethylphenyl, Ts = p-toluenesulfonyl).
