Thereafter, the solvent-free production of bis-coumarins (from aryl aldehydes and 4-hydroxycoumarin) and N,N′-alkylidene bisamides (from aryl aldehydes and benzamide) was catalyzed by NSRISC. Bis-coumarins were produced in 86-97% at 100 ºC, and bisamides were obtained in 87-97% at 105 ºC. The reaction times were 15-30 min for both kinds of compounds.}, number={2}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Atashrooz, Jaleh and Zare, Abdolkarim}, year={2024}, month={Jan.}, keywords={N.
