Небольшая справка:
•Diimines are organic compounds containing two imine (RCH=NR') groups. The most popular derivatives are 1,2-diketones and 1,3-
diimines.
These compounds are used as ligands and as precursors to heterocycles.
•Diimines are prepared by condensation reactions where a dialdehyde or diketone is treated with amine and water is eliminated.
Similar methods are used to prepare Schiff bases and oximes.
Hydrofuramide
•Hydrofuramide is a condensation product of three molar equivalents of furfural with two molar equivalents of ammonia.
Hydrofuramide is a crystalline solid with a melting point of 118-119 °C. The molecule may be described as a diimine with three pendant furanyl rings.
•Hydrofuramide has shown effectiveness as a synergist with zinc stearate, in enhancing the rate of vulcanization of styrene-butadiene rubber. Similar synergistic effect was seen in the vulcanization of natural rubber with hydrofuramide-sulfenamide activator, where introduction of hydrofuramide reduced induction time, scorch time and optimum cure time.
