110-70-3, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular.110-70-3, name is N1,N2-Dimethylethane-1,2-diamine. A new synthetic method of this compound is introduced below.
36.2 g (0.40 mol) acrylic acid chloride and 16 mg MEHQ were dissolved in 600 ml methylene chloride in a 1.5-l sulphonation flask and cooled to -5 C. Then, a mixture of 17.6 g (0.20 mol) N,N’-dimethylethylenediamine, 40.8 g (0.40 mol) triethylamine and 400 ml methylene chloride was added dropwise accompanied by stirring so that the temperature remained between -5 and 0 C. After 1.5 h stirring, the mixture was allowed to warm up to room temperature, stirred overnight, the precipitate formed was filtered off and the filtrate concentrated under vacuum. The raw product was taken up in 150 ml acetone, filtered through a frit with 50 g silica gel 60 and concentrated again. After repeating this process, 30.1 g (77% yield) of a light yellow liquid remained. 1H-NMR (400 MHz, CDCl3): delta=3.10 and 3.14 (s; 2*3H, CH3), 3.54-3.67 (2m; 4H, CH2N), 5.68, 6.35 and 6.56 (m; 3*2H, CH=CH2) ppm.
110-70-3, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,110-70-3 ,N1,N2-Dimethylethane-1,2-diamine, other downstream synthetic routes, hurry up and to see
