Synthesis of functionally substituted 2-cyanoacrylates

Article abstract of DOI:10.1007/BF00699831

The conditions for the Knoevenagel synthesis of 2-cyanoacrylates containing double and triple bonds in the alkoxycarbonyl group have been studied.It was found that the esters are formed in 10-70percent yields by the condensation of the respective cyanoacetates with formaldehyde in the 1:1 ratio in the presence of piperidine, followed by the pyrolysis of the oligomers formed in vacuo at 170-200 deg C in the presence of para-toluenesulfonic acid.The compounds synthesized readily undergo polymerization at room temperature and can be used as the basis for themostable readily polymerizing adhesives. - Key words: cyanoacetates, 2-cyanoacrylates, paraform, formaldehyde, 2-cyanoacrylates.
