Synthesis of new polyurethanes based on 5, 6, 7, 8 – tetrabromo – 2, 3 – dihydro – 1, 4 – phthalazine dione
In this work, 5,6,7,8-Tetrabromo-2,3-dihydro-2,3-bis(2-hydroxyethyl)phthalazine-1,4-dione is synthesized by the reaction of 5,6,7,8-tetrabromo-2,3-dihydrophthalazine-1,4-dione with 2-bromoethanol in the presence of triethylamine. The obtained monomer was polymerized with different diisocyanates, including hexamethylenediisocyanate (HMDI), tolylene-2,4-diisocyanate (TDI), isophoronediisocyanate ...
متن کاملSynthesis and Biological Screening of 4-Benzyl-2H-phthalazine Derivatives
Preparation of 4-benzyl-2-substituted phthalazin-1-one derivatives 2-8 is reported. Condensation of 4-benzyl-1-chlorophthalazine (9) with a series of different nucleophiles gave 4-benzylphthalazin-1-ylamino derivatives (10-13 and 16) and 4-amino-2-[N'-(4-benzylphthalazin-1-yl)-hydrazino]-6-arylpyrimidine-5-carbonitriles (14a,b). Interaction of 9 with ambident anions was also studied. 5-Benzyl-6...
متن کاملMethyl 4-(4-fluorophenyl)-6-isopropyl-2-[N-methyl-N-(methylsulfonyl)amino]pyrimidine-5-carboxylate
In the mol-ecule of the title compound, C(17)H(20)FN(3)O(4)S, the pyrimidine and benzene rings are oriented at a dihedral angle of 35.59 (3)°. Intra-molecular C-H⋯N and C-H⋯O hydrogen bonds result in the formation of one five- and two six-membered non-planar rings. One of the six-membered rings adopts a chair conformation, while the other six-membered ring and the five-membered ring exhibit env...
متن کاملMethyl 4-(4-fluorophenyl)-6-isopropyl-2-(methylsulfonyl)pyrimidine-5-carboxylate
The asymmetric unit of the title compound, C(16)H(17)FN(2)O(4)S, contains three independent mol-ecules, in which the pyrimidine and benzene rings are oriented at dihedral angles of 41.72 (3)°, 26.21 (3)° and 36.49 (3)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two six- and one seven-membered non-planar rings, which have have twist conformations. In the crystal structure, ...
متن کامل(4-Aza-1-azoniabicyclo[2.2.2]octane-κN 4)trichloridocobalt(II)
In the title compound, [CoCl(3)(C(6)H(13)N(2))], the tetra-hedrally coordinated Co(II) ion has Co-Cl distances ranging from 2.2220 (11) to 2.2449 (9) Å and a Co-N distance of 2.056 (2) Å. In the crystal, N-H⋯Cl hydrogen bonds link mol-ecules into chains in [010]. Weak C-H⋯Cl inter-actions stabilize further the crystal packing.
