Transition-metal-catalysed, redox-neutral dehydrosilylation of alkenes is a long-standing challenge in organic synthesis, with current methods suffering from low selectivity and narrow scope. In this study, we report a general and simple method for the manganese-catalysed dehydrosilylation and hydrosilylation of alkenes, with Mn2(CO)10 as a catalyst precursor, by using a ligand-tuned metalloradical reactivity strategy. This enables versatility and controllable selectivity with a 1:1 ratio of alkenes and silanes, and the synthetic robustness and practicality of this method are demonstrated using complex alkenes and light olefins. The selectivity of the reaction has been studied using density functional theory calculations, showing the use of an iPrPNP ligand to favour dehydrosilylation, while a JackiePhos ligand favours hydrosilylation. The reaction is redox-neutral and atom-economical, exhibits a broad substrate scope and excellent functional group tolerance, and is suitable for various synthetic applications on a gram scale.

Alkenes (RCH=CH2, where R = C6H5, p-CH3C6H4, p-CH3OC6H4, p-ClC6H4, 2-naphthyl, (CH3)3C, Me3SiO(CH3)2C, n-C4H9O, and Et3Si) with HSiEt3 with Ru3(CO)12 as a catalyst gave corresponding vinylsilanes (1, 6-13) without formation of simple addition products.Hydrosilanes such as HSiMe3, HSiEt2Me, HSiPhMe2, and HSi(OEt)3 also yielded vinylsilanes.Alkenes having a hydrogen atom at the allylic position (1-hexene, allylbenzene, 3-phenoxyprop-1-ene, vinylcyclohexane, β-methylstyrene, α-methylstyrene, 2-hexene) formed mixtures of vinylsilanes and allylsilanes.The ratio of vinylsilane 16 to allylsilane 17 decreased with an increase in temperature and with time.Substituted styrenes with a hydrosilane in the presence of 1-hexene gave vinylsilanes 1 and 6-8 in good yields based on the styrenes along with n-hexane.
