Aliphatic ditopic nitrile N-oxide crosslinker: Synthesis, chemical stability, and catalyst-free crosslinking reactions
Nitrile N-oxides are useful reagents and crosslinkers for catalyst- and byproduct-free 1,3-dipolar cycloaddition reactions. The stability of nitrile N-oxides can be enhanced by introducing bulky substituents, whereas their reactivity decreases concomitantly. Herein, an isolatable aliphatic ditopic nitrile N-oxide was synthesized and applied to catalyst-free crosslinking of unsaturated bond-containing polymers. By decreasing the steric hindrance around the nitrile N-oxide moiety compared with a related crosslinker previously developed in our group, the operating temperature of the crosslinking reaction could be lowered. Efficient crosslinking of natural rubber (NR) was achieved at 40 degrees C in chloroform to give crosslinked NR without formation of byproducts. Furthermore, polyacrylonitrile and nitrile butadiene rubber can be used as the scaffolds for efficient catalyst- and solvent-free crosslinking reactions.
