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.

标 题:Synthesis of 2-keto-1,4-diazacycloalkanes with a soft ion catalyst
发明人：LAI JOHN T
权利人:GOODRICH CO B F
摘要:A phase transfer catalyzed 'soft ion synthesis' is disclosed in which the presence of a 'soft ion' generated in situ by a soft ion catalyst has a directive effect which favors the formation of a polysubstituted 2-keto-1,4-diazacycloalkane isomer having substituents on both N4-adjacent carbon atoms ('C atoms') of its diaza ring; this isomer is formed at the expense of isomers in which an N4-adjacent C atom is not substituted. Such an isomer which has substituents on each N4-adjacent C atom is generally more effective as a u-v light stabilizer than an isomer which has an unsubstituted N4-adjacent C atom, and therefore the former is more desirable. A liquid phase reaction of an acyclic 1,2-diamine with a monoketone or monoaldehyde in the presence of a phase transfer catalyst, a haloform and alkali is disclosed, in which reaction a soft ion catalyst which generates a soft ion selected from the group consisting of cyanide, iodide and thiocyanate, has a directive effect on the reaction so as to produce more isomer with substituents on each N4-adjacent C atom than would be formed, under identical conditions but without the presence of the soft ion. The directive effect of the soft ion appears to enhance any directive effect that a particular phase transfer catalyst may exhibit.

标 题:Synthesis of 5-cyano-1-hydrocarbylpyrrole-2-acetic acid
发明人：DAGANI MICHAEL J
权利人:ETHYL CORP
摘要:When reacting a 2,2,2-trichloro-1-(N-hydrocarbylpyrryl-2)-ethanol in solution with a cyanating reagent under basic conditions, advantages are achieved by performing the reaction in an aqueous reaction medium containing at least 3 equivalents of calcium hydroxide per mole of the 2,2,2-trichloro-1-(N-hydrocarbylpyrryl-2)-ethanol used in the reaction. Good yields are achieved in short reaction times. Large excesses of cyanating reagents are not required. It is unnecessary to add components to the reaction vessel on a periodic basis in order to achieve good yields. And it is possible to isolate the desired product in the form of a calcium salt by a facile procedure. This enables the desired product to be formed by acidification of the isolated calcium salt without the hazards of toxic HCN generation.

摘要:The present invention relates to a process for preparing 3-cyano-3,5,5-trimethylcyclohexanone (isophoronenitrile) by reacting isophorone with hydrogen cyanide in the presence of a base as a catalyst to obtain a crude isophoronenitrile product, and subsequently distilling the crude isophoronenitrile product, with the addition before distillation of at least one specific sulfonic acid or specific carboxylic acid. In addition, the present invention relates to the use of a specific sulfonic acid or of a specific carboxylic acid as a neutralizing agent before distillation of a crude isophoronenitrile product which has been obtained by reacting isophorone with hydrogen cyanide in the presence of a base as a catalyst, in order to avoid precipitates in the neutralization of the base used as a catalyst with an acid.
