A direct visible light-induced generation of a hybrid aryl Pd-radical species from aryl iodide and Pd(0) is reported to enable an unprecedented (for hybrid Pd-radical species) hydrogen atom-transfer event. This approach allowed for efficient desaturation of readily available silyl ethers into synthetically valuable silyl enols. Moreover, this oxidation reaction proceeds at room temperature without the aid of exogenous photosensitizers or oxidants.
Base-free dehydrogenative coupling of enolizable carbonyl compounds with silanes

A dehydrogenative coupling between enolizable carbonyl compounds and equimolar amounts of triorganosilanes catalyzed by a tethered ruthenium complex with a Ru-S bond is reported. The complex is assumed to fulfill a dual role by activating the Si-H bond to release a silicon electrophile and by abstracting an α-proton from the intermediate silylcarboxonium ion, only liberating dihydrogen as the sole byproduct. Reaction rates are exceedingly high at room temperature with very low loadings of the ruthenium catalyst.

1,4-Addition product was afforded exclusively by rhodiumphosphine complex-catalyzed hydrosilylation by using 2-cyclohexen-1-one and a dihydrosilane bearing an ether substituent in spite of the fact that dihydrosilanes were believed to give 1,2-addition product selectively. Copyright
Dirhodium(II) tetrakis(perfluorobutyrate)-catalyzed 1,4-hydrosilylation of α,β-unsaturated carbonyl compounds

Exposure of an enone to a catalytic quantity of [CuH(PPh3)]6 in the presence of one of several silyl hydrides (PhMe2SiH, PMHS, HMe2SiOSiMe2H) leads to conjugate reduction with concomitant formation of the corresponding silyl enol ether. Without isolation, treatment of these intermediates with a Lewis acid at low temperatures in the presence of an aldehyde, or with fluoride ion together with an activated halide, affords good yields of the product of 3-component coupling (3-CC) in a single reaction flask.
