supporting information, p. 3186 - 3189 (2016/07/14)
Air-stable, thermally robust, and well-defined cationic Ni(II) PNP pincer complexes based on the 2,4-diaminotriazine scaffold are described. These complexes are active catalysts for the Suzuki-Miyaura cross-coupling of a wide range of aryl, heteroaryl (including benzoxazole, thiazole, pyridine, pyrimidine, thiazole), primary and secondary alkyl halides, and pseudohalides with different organoboronate reagents giving excellent to good isolated yields. Neutral deprotonated complexes seem to play a key role in the catalytic process.

-
Page/Page column, (2014/07/07)
The present invention relates to a method for obtaining a triazine compound with at least one tertiary amino group comprising the steps of a) providing at least one triazine compound of the general formulae (I) wherein - R1 and R2 mean independently from each other Q1 or a moiety of the formula R3-N-R4 or R5-N-R6 bound with its central nitrogen atom to the triazine ring of the structure of formula (I), whereat - Q1 means H, hydroxyl, a linear or branched C1-C30-alkyl or a cyclic substituent in form of a C5-C20-cycloalkyl, a C5-C20-aryl, a C1-C20-alkylsubstituted C5-C20-aryl, wherein in each case one or multiple carbon atoms can be substituted by one or multiple oxygen atoms, sulphur atoms, substituted nitrogen atoms and/or by one or multiple groups of the type - C(O)O-,-OC(O)-,-C(O)- and/or -OC(O)O-, and/or can be functionalized by one or multiple hydroxyl groups and/or mercapto groups - R3, R4, R5 and R6 mean independently from each other H, linear or branched C1-C20-alkyl, C5-C20-cyclo alkyl, C5-C20-aryl, C1-C20-alkylsubstituted C5-C20-aryl, wherein in each case one or multiple carbon atoms can be substituted by one or multiple oxygen atoms, sulphur atoms and/or substituted nitrogen atoms and/or by one or multiple groups of the type -C(O)O-, -OC(O)-, -C(O)- and/or -OC(O)O-, and/or can be functionalized by one or multiple hydroxyl groups and/or mercapto groups; or an amide of a carboxylic acid or an imide of a cyclic dicarboxylic acid, and b) reacting said aminotriazine of the general formulae (I) with at least one secondary amine of the general formulae (II) ???????? (R7R8)NH wherein R7 and R8 are linear or branched C1-C20-alkyl, C5-C20-cycloalkyl, or C1-C20-alkylsubstituted C5-C20-aryl or cyclic amines, or wherein R7 and R8 together form an alkyl ring, wherein in each case one or multiple carbon atoms can be substituted by one or multiple oxygen atoms, sulphur atoms and/or substituted nitrogen atoms and/or by one or multiple groups of the type -C(O)O-, -OC(O)-, -C(O)- and/or -OC(O) O- and/or can be functionalized by one or multiple hydroxyl groups and/or mercapto groups, and wherein R7 and R8 can be the same or different; c) wherein the reaction takes place in the presence of at least one compound of the general formulae (III) ???????? (R9R10)2NH2+]nXn- wherein R9 and R10 are H, linear or branched C1-C20-alkyl, C5-C20-cycloalkyl, or C1-C20-alkylsubstituted C5-C20-aryl or cyclic amines or wherein R9 and R10 together form an alkyl ring, wherein in each case one or multiple carbon atoms can be substituted by one or multiple oxygen atoms, sulphur atoms and/or substituted nitrogen atoms and/or by one or multiple groups of the type -C(O)O-, -OC(O)-, -C(O)- and/or -OC(O) O- and/or can be functionalized by one or multiple hydroxyl groups and/or mercapto groups, wherein R9 and R10 can be the same or different, wherein R7, R8,R9 and R10 can be the same or different, for the case that R9 and R10 are not H wherein Xn- is an anion of an organic or inorganic acid, and wherein n ≥1, in particular 1, 2, 3 or 4.
