Abstract: A process for the production of beta -alkoxy-nitriles which is carried out in the presence of a basic diazabicycloalkene catalyst. Production of beta -alkoxy-nitriles which involves reaction of alpha , beta -unsaturated nitriles with mono-, di- or tri- valent alcohols in the presence of a basic diazabicycloalkene of formula (1), at (-) 20-200 degrees C. n, m = 1-6; and where the 1-4 H atoms are optionally substituted by R -R ; R -R = 1-20C alkyl, 6-20C aryl or 7-20C arylalkyl. An Independent claim is also included for a production process of a gamma -alkoxy-amine by hydrogenation of the beta -alkoxy-nitrile in the presence of a hydrogenation catalyst and the catalyst of formula (1).

Abstract: 6-(p-Acylaminophenyl)-4,5-dihydropyridaz-3-ones of the formula I I where R1 is hydrogen or alkyl of 1 to 3 carbon atoms and R2, if R1 is hydrogen, is halogen-substituted alkyl of 3 to 6 carbon atoms or beta -haloethyl or, if R1 is alkyl of 1 to 3 carbon atoms, is halogen-substituted alkyl of 1 to 6 carbon atoms, their manufacture, and therapeutic agents which contain, as the active ingredient, a compound of the formula I, where R2 may also be halomethyl or alpha -haloethyl if R1 is hydrogen. These compounds may be used as anti-hypertensive agents and for the prophylaxis and therapy of thromboembolic disorders.

Abstract: The parent patent describes the prepn. of N-(2-cyanoethyl) cyclohexylamine or its ring alkyl substd. derivs. by reaction of cyclohexylamine or alkylcyclohexylamine with acrylonitrile at high temp. in the presence of catalytic quantities of acetic acid. The modification of the above process produces bis-(2-cyanoethyl)-ethylenediamine (I) from ethylenediamine. (I) is used to prepare bis-(3-aminopropyl)-ethylenediamine, an important paper-making chemical. High yields are obtd. (over 90%) compared with known processes and the reaction may be carried out at low temps.

Abstract: A method for the N-alkylation of amines by reacting alcohol with (di)alkylamine in the presence of hydrogen is carried out in the presence of a catalyst based on copper and magnesium silicate, which contains 0-2 wt.% each of barium oxide, chromium (III) oxide (Cr2O3) and/or zinc oxide. Also claimed is the use of this catalyst for N-alkylation of amines.

Abstract: Preparation of N-substituted cyclic amines of formula (I) comprises reacting primary amines of formula R NH2 (II) with diols of formula HO-A-OH (III) in the presence of hydrogen and a catalyst containing copper obtained by impregnating an inert support with an aqueous solution of an ammine complex of a Cu compound (IV) that readily undergoes thermal decomposition, then drying and calcining to give a catalyst containing 5-50 wt.% Cu, calculated as oxide. A = alkylene or (CH2)n-ÄO-CH2)mÜr (optionally substituted by one or more R ); R , R = alkyl, alkoxyalkyl, optionally alkyl- or alkoxy-substituted cycloalkyl, cycloalkylalkyl, aryl or arylalkyl; n, m = 2-8; r = 1-3.
