The present invention relates to a novel process for the production of methanol. The process comprises the heterolytic cleavage of hydrogen by a frustrated Lewis pair comprising a Lewis acid and a Lewis base; and the hydrogenation of CO2 with the heterolytically cleaved hydrogen to form methanol.

A palladium-catalyzed intermolecular direct C–H allylation of polyfluoroarenes with alkynes is reported. Unlike classic hydroarylation reactions, alkynes are used as allylic electrophile surrogates in this direct aromatic C–H allylation. As an atom-economic and efficient method, various linear allylated fluoroarenes were synthesized from two simple and easy-to-access feedstocks in good to excellent
Fluorination of polyfluoro-derivatives of benzene and diphenyl with vanadiumpentafluoride at −25 to −10 °C afforded fluorinated cyclohexadienes and cyclohexenes. Octafluoro- naphthalene was converted under these conditions to perfluoro- 1,4-dihydronaphthalene, perfluorotetralin, perfluoro-l,4,5,8- tetrahydronaphthalene and perfluoro-l,2,3,4,5,8-hexahydro- naphthalene.

A copper-catalyzeddirectpropargylation of polyfluoroarenes with secondarypropargylphosphates has been developed. The reaction proceeds under mild reaction conditions with high efficiency and regioselectivity and provides a concise and straightforward method for the synthesis of polyfluoroarylated derivatives of interest in both life and materials science.

ubiquitous Stille coupling reaction utilizes Sn-C bonds and is of great utility to organic chemists. Unlike the B-C bonds used in the Miyaura-Suzuki coupling reaction, which are readily obtained via direct borylation of C-H bonds, routes to organotin compounds via direct C-H bond functionalization are lacking. Here we report that the nickel-catalyzed reaction of fluorinatedarenes and pyridines with vinyl
