A highly efficient rhodium-catalyzed hydrosilylation of N-sulfonyl-1,2,3-triazoles has been developed. The protocol uses readily available N-sulfonyl-1,2,3-triazoles and triphenylsilane as starting materials, and the reactions first gave 2-(triphenylsilyl)-2-aryl-N-(arylsulfonyl)ethanimines, the isomerization of which provided (E)-2-(triphenylsilyl)-2-aryl-N-(arylsulfonyl)ethenamines in the presence of triethylamine; the reduction of which with LiAlH4 led to 2-(triphenylsilyl)-2-aryl-N-(arylsulfonyl)ethanamines. It is worthwhile to note that the obtained products could be converted into indole and arylethylamine derivatives. Therefore, the highly efficient rhodium-catalyzed hydrosilylation method is a valuable strategy for synthesis of diverse compounds.

The construction of C(sp3)-N bonds via direct radical-radical cross-coupling under benign conditions is a desirable but challenging approach. Herein, the cross-coupling of alkyl and amidyl radicals to build aliphatic C-N bonds in a concise, mild, and oxid

A simple copper-based catalytic system has been developed for the carbon-hydrogen amidation reaction. The copper-homoscorpionate complex Tp Br3Cu(NCMe) catalyzes the transfer of the nitrene unit NTs (Ts = p-toluenesulfonyl) and its subsequent insertion into the sp3 C-H bonds of alkyl aromatic and cyclic ethers or the sp2 C-H bonds of benzene using PhI=NTs as the nitrene source, affording the corresponding trisubstitued NR1HTs amines in moderate to high yields. The use of the environmentally friendly chloramine-T has also proven effective, with the advantage that sodium chloride is formed as the only byproduct. A tandem, one-pot consecutive nitrene-carbene insertion system has been developed to yield amino acid derivatives.
