Abstract: It is demonstrated with many examples that conducting mechano-chemical reactions at increased pressure of the gas medium allows one to synthesize new compounds, to conduct catalytic reactions in solid, to find new more efficient routes for reactions, both in inorganic and in fine organic synthesis. At hydrogen pressure of 2-10 MPa, the hydrides of magnesium and intermetallic compounds are synthesized, including previously unknown hydride of the magnesium-copper intermetallide. At increased oxygen pressure, lower oxides of manganese are transformed into active manganese dioxide, which is efficient oxidizer for the processes of fine organic synthesis. Catalytic reactions are conducted under the conditions of mechanical activation at increased pressure of hydrogen, oxygen, and ammonia. Solid-phase hydrogenation of a series of organic compounds allows one to selectively reduce functional groups and unsaturated bonds. Hydro-dechlorination of toxic chlorinated aromatic compounds has been performed, including complete destruction of 1,2,3,4-tetrachlorodibenzo-p-dioxin. At increased oxygen pressure, oxidative transformations of ursolic acid are performed. At increased ammonia pressure, the amide of ursolic acid is obtained. At increased temperature and increased hydrogen pressure, hydro-alumination of heptene-1 and dihydromyrcene is performed, leading to the formation of the corresponding aluminum derivatives R3Al.
