摘要:PCT No. PCT/FR96/02100 Sec. 371 Date Sep. 15, 1998 Sec. 102(e) Date Sep. 15, 1998 PCT Filed Dec. 27, 1996 PCT Pub. No. WO97/24318 PCT Pub. Date Jul. 10, 1997The present invention relates to a method for the synthesis of a halogen substituted aryl nitrile, where the halogens are selected from Cl, Br, or I, by reacting an aryl dihalide with a halogen/fluoride exchange reactant to produce a halogen substituted aryl fluoride which is then reacted with a fluoride/cyanide exchange reactant to produce the halogen substituted aryl nitrile.

摘要:A PROCESS FOR THE EFFICIENT SYNTHESIS OF CYANURIC FLUORIDE IS PROVIDED. THE PROCESS COMPRISES CONTACTING CERTAIN CYANURIC HALIDES WITH SELECTED ALKALI METAL FLUORIDES IN THE PRESENCE OF A PERHALOCARBONYL COMPOUND. THE PROCESS OF THE PRESENT INVENTION PROVIDES FOR THE PRODUCTION OF CYANURIC FLUORIDE AT CONSIDERABLY REDUCED TEMPERATURES, THAN THOSE USED IN KNOWN PROCESSES.

标题:Process for the synthesis of acylated derivatives of fatty acid-transporting thiols and in particular acyl-coenzymes A and the thus obtained acyl-coenzymes A

摘要:The invention relates to a process for the synthesis of an acylated derivative of a fatty acid-transporting thiol such as the coenzyme A. According to this process, a silylated or stannylated thiol is prepared by reacting the thiol with a silylation or stannylation reagent in order to at least partly replace the unstable hydrogens of the thiol by SiR3 or SnR3 groups with R being an alkyl or aryl group. The silylated or stannylated thiol is then reacted in an anhydrous organic medium with an activated organic acid and a deprotection reagent able to eliminate the silyl or stannyl groups. In this way it is possible to obtain acylated derivatives of the coenzyme A, in which the acyl group can have up to 30 carbon atoms with high yields.
