In 2019,European Journal of Chemistry included an article by Nongrum, Stability; Das, Susma; Khanikar, Shikpika; Vishwakarma, Jai Narain. SDS of cas: 4637-24-5. The article was titled 《Synthesis, structural elucidation and X-ray crystallographic studies of 1-(3,5-bis(trifluoromethyl)phenyl)-3-(dimethylamino)prop-2-en-1-one》. The information in the text is summarized as follows:
A new enaminone was synthesized by reacting 3,5-bis-(trifluoromethyl)acetophenone and N,N-dimethylformamide di-Me acetal and its detailed structural and crystalline properties were studied. The crystal data were found to be as C13H11F6NO, monoclinic, space group P21/c (number 14), a = 8.1556(8) Å, b = 24.877(3) Å, c = 7.6067(7) Å, β = 116.745(6)°, V = 1378.2(3) Å3, Z = 4, T = 293(2) K, μ(MoKα) = 0.150 mm-1, Dcalc = 1.500 g/cm3, 40777 reflections measured (5.594° ≤ 2θ ≤ 56.786°), 3413 unique (Rint = 0.1040, Rsigma = 0.0584) which were used in all calculations The final R1 was 0.0771 (I > 2σ(I)) and wR2 was 0.2541 (all data). The experimental part of the paper was very detailed, including the reaction process of N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5SDS of cas: 4637-24-5)
N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. Reaction with nitrous acid (HNO2), which functions as an acylating agent that is a source of the nitrosyl group (―NO), converts aliphatic primary amines to nitrogen and mixtures of alkenes and alcohols corresponding to the alkyl group in a complex process. This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.SDS of cas: 4637-24-5
