These research results belong to Abdel-Aziz, Alaa A.-M.; El-Azab, Adel S.; Ghabbour, Hazem A.; Obaidullaha, Ahmad J.. Name: N,N-Dimethylformamide Dimethyl Acetal The article mentions the following:
C9H13N3O2S, monoclinic, P21/c (number 14), a = 8.0984(4) Å, b = 17.3203(10) Å, c = 9.6802(4) Å, β = 124.031(3)°, V = 1125.26(10) Å3, Z = 4, Rgt(F) = 0.0504, wRref(F2) = 0.1275, T = 293(2) K. CCDC number: 1514612. A mixture of benzenesulfonamide (344 mg, 2 mmol) and N, N-dimethylformamide di-Me acetal (476 mg, 4 mmol) in ethanol (10 mL) was heated under reflux for 10 h. The reaction mixture was cooled and the separated solid was filtered, dried and recrystallized from ethanol. Yield 96%; 1H NMR (DMSO-de; 500 MHz): δ 8.10 (s, 1H, N-C(H)=N), 7.39-7.37 (d, 2H, j = 8.5 Hz, Ar-H), 6.58-6.56 (d, 2H, j = 9.0 Hz, Ar- H), 5.82 (s, 2H, NH2), 3.10 (s, 3H, CH3), 2.87 (s, 3H, CH3) ppm; 13C NMR (DMSO-de; 125 MHz): δ 35.30 (CH3), 41.14 (CH3), 113.01, 128.20, 129.03, 152.41, 159.43 (N-CH=N) ppm; MS: m/z = 227.1.N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Name: N,N-Dimethylformamide Dimethyl Acetal) was used in this study.
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).Name: N,N-Dimethylformamide Dimethyl Acetal
