Paragraph 0030-0033; 0038-0045, (2021/03/31)
The invention belongs to the technical field of organic synthesis, and particularly relates to a preparation method of (benzene-1, 3, 5-triacyl) triacetonitrile. The reaction reagent is a mixed solvent of DMSO and water, and water is added, so that the solubility of reactants of potassium cyanide is improved, generated potassium chloride and potassium bromide are promoted to enter a water phase intime, the reaction can be carried out in the forward direction, the reaction time is shortened, and the conversion rate of raw materials is remarkably increased; catalytic equivalent organic alkali is added into a reaction system, so that the leaving of halogen ions is promoted, the efficiency of a forward reaction is promoted, and the product is easier to separate and purify; the reaction time is at least shortened by 13-142 hours compared with the reported reaction time, a large amount of time cost is saved, and the efficiency of quantitative production of products is improved; and the preparation process is simple and easy to control, the raw material conversion rate is high, the target product yield is 94.5% or above, the residual quantity of highly toxic substances is obviously reduced, and the experiment safety is improved to the maximum extent.

Synthesis of bis- and tris(indolinylidenemethyl)benzenes by one-pot reactions of polylithiated nitriles with bis(imidoyl)chlorides of oxalic acid
Langer, Peter,Anders, Joachim T.
, p. 686 - 691 (2007/10/03)
The reaction of polylithiated di- and tricyanomethylbenzenes with oxalic acid-bis(imidoyl)chlorides afforded novel oligo(indolinylidenemethyl)benzenes with the formation of up to six carbon-carbon bonds. The UV/Vis spectroscopic features of these and related compounds were studied. 1,4-Disubstituted benzenes containing a large π-system have been efficiently prepared by the reaction of dianions with 1,4-dicyanobenzene.
