First copper(I) chalcogenones catalysed Knoevenagel Condensation reactions have been reported. No illustration of the utilization of this copper-chalcogenone complex class in Knoevenagel Condensation catalysis can be found. Thus, copper(I) bis(benzimidazole-2-chalcogenone) catalysts [Cu(L1)4]+BF4? (1) and [Cu(L2)4]+BF4? (2) (L1 = bis(1-isopropyl-benzimidazole-2-selone)-3-ethyl; L2 = bis(1-isopropyl-benzimidazole-2-thione)-3-ethyl) have been utilized as catalysts in the Knoevenagel Condensation reactions. These copper(I) chalcogenone catalysts have shown high efficiency for the catalytic Knoevenagel Condensation of aryl aldehydes and active methylene compounds. In particular, complex 2, exhibit the best catalytic activities. The scope of the catalytic reactions has been investigated with 22 different molecules. The excellent catalytic activity has been depicted for various types of substrates with either electron-rich or deficient aryl aldehydes. The present investigation features relatively mild reaction conditions with good functional group tolerance and excellent yields. Graphic Abstract: The first copper(I)-chalcogenone complexes catalysed Knoevenagel Condensation reactions?have also been investigated, and revealed the best catalytic activities.

The invention discloses a green and efficient synthesis method for an aryl acrylonitrile compound represented by formula III. The method comprises the following steps: in an air atmosphere, by takingaryl acetonitrile of formula I as shown in the specification and excess methyl cyanoacetate of formula II as shown in the specification as raw materials, and Ru/C as a catalyst, enabling the components to react at 150-160 DEG C in the absence of a solvent, and separating and purifying a reaction mixture obtained after the reaction is completed, thereby obtaining an aryl acrylonitrile compound of formula III as shown in the specification. The method disclosed by the invention is not only low in production cost, but also good in environment protection, and is very applicable to industrial large-scale production.
