Jc. Feng et al., ONE-STEP CONVERSION OF ALDEHYDES INTO NITRILES IN DRY MEDIA UNDER MICROWAVE IRRADIATION, Synthetic communications, 28(20), 1998, pp. 3765-3768
Aldehydes undergo rapid reaction with hydroxylammonium chloride using
HCOOH/SiO2 as solid support catalyst, under microwave irradiation with
out solvent to affords nitriles in 60-90% yields.
