A newly developed methodology for the use of organosilanes as radical precursors under metal-free and visible-light conditions is presented. The strong oxidant character of the 9-mesityl-10-methylacridinium salt in its excited state enables the transforma
Decatungstate photocatalyzed benzylation of alkenes with alkylaromatics

The direct benzylation of electrophilic al-kenes with alkylbenzenes has been achieved by decatungstate photocatalysis in a high ionic strength medium (5:1 acetonitrile/water mixed solvents, 0.5 M lithium perchlorate). The reaction has been extended to ring-substituted (Cl, F, CN) toluenes and further alkylbenzenes. Intramolecular selectivity (p-cymene, 4-methylanisole) and deuteration effects support the atom transfer character of the process that, however, requires a sufficient stabilization of the intermediate polar exciplex to occur. The reactivity of the deca-tungstate anion is compared with that of aromatic ketones, the benchmark of photochemical hydrogen/ electron transfer processes.
Decatungstate as photoredox catalyst: Benzylation of electron-poor olefins

Excited tetrabutylammonium decatungstate (TBADT), known to activate a variety of compounds via hydrogen atom transfer (HAT), has now been applied as a photoredox catalyst for the effective oxidative cleavage of benzyl silanes and radical benzylation of reducible olefins occurring in isolated yields from poor to excellent.
A practical method for the reductive cleavage of the sulfide bond in xanthates
Liard, Annie,Quiclet-Sire, Beatrice,Zard, Samir Z.
, p. 5877 - 5880 (2007/10/03)
Xanthates can be reduced to the corresponding alkane through cleavage of the sulfide bond by heating in 2-propanol in the presence of equimolar amounts of dilauroyl peroxide, added in small portions.
