The hydrosilylation of alkene substrates bearing additional functionalities is difficult to achieve using earth-abundant catalysts and has not been extensively realized with both earth-abundant transition metals and tertiary silanes or hydrosiloxanes. Reported herein is a well-defined bis(carbene) cobalt(I)-dinitrogen complex for the efficient, catalytic anti-Markovnikov hydrosilylation of terminal alkenes, featuring a broad substrate scope. Alkenes containing hydroxyl, amino, ester, epoxide, ketone, formyl, and nitrile groups are selectively hydrosilylated in this reaction sequence. Multinuclear NMR studies of reactive intermediates gave insights into the mechanism.

The ligands on a silicon atom in allylsilanes were found to influence the efficiency of their reaction with ketones in the presence of MnO2. An electron-donating group on silicon provided a promoting effect, yet the steric effect of a bulky sil

Platinum nanoparticles were stabilized at the surface of carbon nanotubes and the nanohybrid was valorized as a catalyst for the hydrosilylation of alkenes and alkynes. The heterogeneous catalyst operated under sustainable conditions (room temperature, no solvent, low catalyst loading, air atmosphere) and exhibited improved stabilty as recycling and reuse could be achieved for multiple consecutive reactions.

Although there has been significant progress in the development of transition-metal-catalyzed hydrosilylations of alkenes over the past several decades, metal-free hydrosilylation is still rare and highly desirable. Herein, we report a convenient visible-

Phenyldimethylsilane and trichlorosilane are shown to undergo efficient radical hydrosilylation reactions, on reaction with various alkenes, using triethylborane as the initiator. Adducts from the trichlorosilane reactions can be oxidised to afford alcohols in good yields. This two-step process leads to the anti-Markovnikov hydration of alkenes.
