标 题:Chiral and achiral synthesis of 2-acyl substituted chromanes and their derivatives
发明人：KANTER JAMES; MARLOWE CHARLES; PANDEY ANJALI; MULLINS JOHN J G; SCARBOROUGH ROBERT; BUTKE GREG; JACOBSON BARRY; WALKER DEREK
摘要:Disclosed are processes for producing a (2S) or (2R) 4-oxo-chroman-2-yl acyl compounds and chroman-2-yl acyl compounds, esters or amides thereof as well as derivatives thereof. Such processes may involve chiral synthesis or achiral synthesis, preferably coupled with a resolution procedure. Such compounds, particularly (2S) or (2R) acetic acid esters, are useful intermedates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors. Further disclosed are processes for making derivatives of such substantially pure, or enhanced compositions of single (2R) or (2S) enantiomer intermediates or processes for producing final products or salts from such desired enantiomers.

标题 :Treatment of aromatic amines with gas mixtures derived from the oxidation of ammonia to effect diazotization/coupling

摘要:1,3-Diaryl triazenes, e.g., 1,3-diphenyltriazene, intermediates in the synthesis of aromatic diamines, e.g., p-phenylenediamine, are prepared by catalytically oxidizing ammonia, and subsequently the resulting nitric oxide, with a gas comprising diluted molecular oxygen, e.g., air, so as to produce a gas mixture containing dilute NOx, i.e., NO2 preferably admixed with NO, x being (1 + n), wherein n is the NO2 fraction of the NOx; and contacting the gas mixture, preferably at a temperature in the range of about from 25 DEG to 350 DEG C., with excess primary aromatic monoamine, e.g., aniline, so as to result in a monoamine temperature in the range of about from 25 DEG to 90 DEG C., preferably 40 DEG to 60 DEG C., during contact. Highest yields of triazene are obtained when the x in NOx is about from 1.3 to 1.7, and the amount of NOx gas mixture contacted with the monoamine and the time of contact are such that at least about 60% by weight of the monoamine remains unconsumed. A gas mixture temperature just prior to gas contact with the liquid monoamine in the range of about from 110 DEG to 275 DEG C. is more preferred under certain circumstances.

标题 :Process for the synthesis of nitrite ion-containing 1:1 complexes of cobalt and metallizable monoazo or azomethine compounds and such complexes
发明人：DORE JACKY
权利人:SANDOZ LTD
摘要:By metallization of metallizable monoazo or azomethine dyes with cobalt-donating compounds in the presence of a nitrite, especially NaNO 2 , 1:1 cobalt complexes containing a nitrite ion are obtained in a high degree of metallization which can be reacted with metallizable monoazo or azomethine dyes to give very homogeneous 2:1 cobalt complexes in a high degree of purity. This is particularly advantageous when asymmetrical 2:1 cobalt complexes are to be prepared. The process is particularly useful for the preparation of nitrite ion-containing 1:1 complexes of cobalt and a monoazo compound of the formula ##STR1## wherein X is --OH or --NHR, n wherein R is hydrogen or a substituted or unsubstituted alkyl, cycloalkyl, phenyl or naphthyl group, n Ring A is further unsubstituted or further substituted by at least one halo, nitro or optionally substituted alkyl, alkoxy or sulfamoyl substituent, and n The naphthalene ring is further unsubstituted or further substituted by at least one hydroxy, sulfamoyl or acylamino substituent.

标题 :Process for the synthesis of ammonium nitrite

摘要:Ammonium nitrite is commercially produced by contacting a gaseous stream containing nitric oxide, nitrogen dioxide, nitrogen and oxygen with an aqueous solution containing a basically reacting ammonium compound in an absorption system. However, at normal production rates, serious problems have been encountered because of relatively low yield of ammonium nitrite and the emission of unreacted nitric oxide which causes pollution of the atmosphere. It has now been found that in situ generation of nitrogen dioxide in the absorption system by operating the absorption system under slight pressure greatly improves ammonium nitrite yield, reduces nitrogen oxide emission, reduces loss of ammonia as nitrogen and minimizes mist formation in the vent gas. Moreover, with respect to environmental pollution, we have discovered that a synergistic improvement results from an interaction effect involving use of said sight pressure in combination with late addition of controlled supplemental quantities of nitrogen dioxide to the nitrogen oxide gas while said gas is being absorbed in the absorption system.
