Crystal structures of seven terephthaldiamide derivatives

N,N′-Dibutyl-terephthaldiamide (1), N,N′-dihexyl-terephthaldiamide (2), N,N′-di(tert-butyl)-terephthaldiamide (3), N,N,N′,N′-tetrabutyl-terephthaldiamide (4), 1,1′-terephthaloyl-bis-pyrrolidine (5), 1,1′-terephthaloyl-bis-piperidine (6), and 4,4′-terephthaloyl-bis-morpholine (7) have been synthesised and physicochemically characterised. The X-ray structure determinations reveal imposed inversion symmetry for compounds 1-6; compound 3 has two independent molecules with inversion symmetry in the asymmetric unit. Compounds 1-3 form classical hydrogen bonds of the type N-H?O=C, leading to a ribbon-like arrangement of molecules (1 and 2) or a layer structure (3). Compound 3 also displays a very short C-H?O interaction, a type of hydrogen bond that is also observed in compounds 4-7, which lack classical donors; thereby compounds 4-6 form layer structures and 7 a complex three-dimensional network.

Efficient microwave access to polysubstituted amidines from imidoylbenzotriazoles

Microwave reactions of primary and secondary amines with imidoylbenzotriazoles 6a-w gave diversely substituted amidines 7a-Aa in 76-94% yields. Convenient preparations of a variety of amides 5a-Ab (87-96%) and imidoylbenzotriazoles 6a-w (56-95%) have also been developed using microwave irradiation under mild conditions and short reaction times. These results demonstrate further the advantages of microwave synthesis and introduce a new application of imidoylbenzotriazoles in the preparation of polysubstituted amidines.

POLYAMIDE-BOUND METAL COMPLEX CATALYSTS:SYNTHESIS, CHARACTERIZATION AND CATALYTIC PROPERTIES

A series polyamides having different numbers of methylene groups in their repeating units have been synthesized by interfacial polycondensation of terephthaloyl chloride with piperazine and aliphatic diamines H2N(CH2)nNH2 (n = 2, 6, 10).These m

Aminolysis of N-acyllactams

The overall second-order rate constants of aminolysis of N-benzoyllactams of different ring size, the rate constants of aminolysis of N,N'-isophthaloyl- and N,N'-terephthaloylbis(6-hexanelactam) to the first and second stages and the ratio of splitting of the exocyclic and endocyclic amide bond by octylamine were determined in THF at 50 deg C.The effect of the type of amine and medium on the rate of aminolysis was examined.

Preparation of alkylcarboxamides

A process for the preparation of N-substituted alkylcarboxamides from a nitrile which comprises subjecting said nitrile to an aqueous non-catalytic hydrolysis to obtain an essentially equilibrium mixture consisting essentially of carboxamide and ammonium carboxylate salt, cooling said equilibrium mixture and isolating a crystalline mixture of carboxamide and ammonium carboxylate, reacting an alkylamine with the isolated mixture, filtering the reaction mass to separate insoluble carboxamide, and contacting the filtrate with a dehydration catalyst to obtain said N-substituted alkylcarboxamide in high yield.
