An H-bonding-induced radicaladdition of simple alcohols to unactivated olefins was achieved. It effectively solved the long-standing problems of reactivity and selectivity in this type of reactions. The hydroxyalkylation occurred via site-specific cleavage of the α-hydroxyl-C-H bond in alcohols. This method allows a highly atom-economic, operationally simple and environmentally benign access to diverse

Ni/SiO2–Al2O3 (Ni/SA) catalyst was investigated for hydrocyclisation of levulinic acid (LA) to γ-valerolactone (Gvl) in presence of different hydrogensources such as molecular hydrogen, isopropyl alcohol (IPA), and formic acid. At optimized reaction condition (200 °C, 10 bar H2 for 30 min), the Ni/SA catalyst showed 100% yield of Gvl using molecular H2 in tetrahydrofuran (THF) medium. The catalyst also exhibited

strategy by which a hydrophobic mixture of butyl levulinate and formateesters, derived from cellulosic biomass, can be converted to valuable γ‐valerolactone (GVL) by a simple supportedgoldcatalyst system without need of an external hydrogen source. The essential role of the supportedgold is to facilitate the rapid and selective decomposition of butyl formate to produce a hydrogen stream, which enables
