Benzylic silanes bearing an electron-donating group at the ortho- or para-position underwent the oxovanadium(V)-induced one-electron oxidative desilylation due to low ionization potential, which was applied to the intermolecular regioselective coupling with allylic silanes or silyl enol ether.
The present invention relates to a fragrance composition comprising ionic liquids for enhanced evaporation of the perfume raw materials. The invention also relates to methods of use of the fragrance compositions for perfuming suitable substrates, particularly skin and hair.

Hydrodeoxygenation and reductive etherification of biomass-derived aldehydes were realized on the same Pd/TiO2 photocatalyst via photocatalytic transfer hydrogenation using aliphatic alcohols as hydrogen donor, and the selectivity was easily switched by the substrate concentration.
