Pd(0)–Ru(iii)/diamine-functionalized periodic mesoporous organosilica for asymmetric transfer hydrogenation–Sonogashira coupling of iodoacetophenone and arynes is investigated.
Isocyanurate bridging periodic mesoporous organosilica (PMO-ICS) was shown to be a highly active and efficient recyclable nanocatalyst for three-component synthesis of trisubstituted imidazole as well as benzimidazole derivatives in EtOH.
