摘要:The present invention relates to a new process for the preparation of a bimetallic ruthenium/tin catalyst. The process for the preparation of a bimetallic ruthenium/tin catalyst according to the invention is characterised by the fact that it consists in carrying out the reduction of a ruthenium complex having an electrovalency of -4 and a coordination number of 6, the ligands being either a halogen atom or an anion or a tin halide. The catalyst is further employed for the preparation of aldehydes by reduction, in the vapor phase, of carboxylic acids, esters and anhydrides.

摘要:New fluorinated substituted ethylenic compounds which are 2,3,4,5,6-pentafluoro- Alpha -(trifluoromethyl) benzyl alcohol, (1,2,2,2-tetrafluoroethyl)perfluorobenzene and (1-bromo-1,2,2,2tetrafluoroethyl)perfluorobenzene. The new compounds are useful as intermediates in the preparation of perfluorostyrene. Pyrolysis of the aforesaid perfluorobenzenes gives perfluorostyrene and of the first of these perfluorobenzenes, Alpha -hydroheptafluorostyrene, also.

摘要:PCT No. PCT/FR96/00101 Sec. 371 Date Jul. 31, 1997 Sec. 102(e) Date Jul. 31, 1997 PCT Filed Jan. 22, 1996 PCT Pub. No. WO96/22832 PCT Pub. Date Aug. 1, 1996The present invention relates to a composition which can be used as reduction catalyst. This composition is characterized in that it comprises a support whose constituent material comprises at least one oxide chosen from oxides which are inert or capable of being made inert relative to the reaction mixture and a phase at least partially covering the said support, of which at least part comprises an intermetallic ruthenium-tin compound of composition Ru3Sn7. The invention also describes the use of the reduction catalyst and its application to organic synthesis.
