A photocatalytic dearomative hydrosilylation reaction of indole derivatives with silanes has been accomplished for the synthesis of valuable indolinyl silanes through a carbon-silyl radical coupling process with the cooperation of photoredox and hydrogen atom transfer catalytic systems composed of 3DPA2FBN (2,4,6-tris(diphenylamino)-3,5-difluorobenzonitrile), (i-Pr)SiSH, and base additives. This protocol is featured by a broad substrate scope, transition metal-free conditions, high diastereoselectivities and applications in natural product derivatives.

The selective and efficient synthesis of (E)-1,2,4-trisilylbut-1-en-3-ynes obtained via Pt-catalyzed hydrosilylation of 1,4-bis(trimethylsilyl)buta-1,3-diyne is described. Optimized reaction conditions (Pt(PPh)) or Pt(dvs), 100 °C, toluene, 18 h) yielded compounds with high isolation yields (76-95%). The modification of (E)-1,2,4-trisilylbut-1-en-3-ynes was further tested in protodesilylation, halodesilylation, hydrosilylation, and Pd-based cross-coupling reactions, resulting in a broad spectrum of new products.

Porous silicon is one of the most explored nanostructured materials in various biomedical applications owing to its remarkable properties. However, its inherent chemical instability mandates a robust surface modification procedure, and proper surface bioengineering is essential to ensure its effectiveness in the biomedical field. In this study, we introduce a one-pot functionalization strategy that simultaneously stabilizes porous silicon nanoparticles and decorates their surface with carbohydrates through hydrosilylation chemistry, combining mild temperatures and a Lewis acid catalyst.

The 5,6-Bis(diisopropylphosphino)acenaphthene -stabilized Sb(I) cationic compound [LSb][OTf] (OTf = CFSO) possessing two lone pairs of electrons on the Sb(I) center showed nucleophilic behavior toward methyl trifluoromethanesulfonate forming the oxidized product [LSbMe][OTf] (OTf = CFSO). Reaction of compound with Lewis acids such as GaCl and AlBr led to changes in the counteranions only giving products [LSb][GaCl] and [LSb][SbBr] , respectively. A metathesis reaction was observed when compound was reacted with PI.

Reported herein is a convenient and efficient method for one-pot, catalytic reductive amination, as well as the first multi-component tandem reductive amination-functionalization of bench-stable and readily available common carboxylic esters. This method is based on the cationic [Ir(COD)]BArF-catalyzed chemoselective hydrosilylation of esters, followed by one-pot acid-mediated amination and nucleophilic addition. The reaction was conducted under mild conditions at a very low catalyst loading (0.
