Heteropolyanion-based sulfated ionic liquid catalyzed formamides synthesis by grindstone chemistry
摘要:
A novel heteropolyanion-based sulfated ionic liquid (HIL[Ch-OSO3H](3)W-12 PO40) was prepared by pairing sulfate functionalized cholinium cation [N,N,N-trimethyl-2-(sulfooxy)ethanaminium] with catalytically active phosphotungstic acid anion (W12PO403-). It was characterized by H-1 NMR, EDX, XRD,TGA and elemental analysis. Catalytic activity of thus prepared HIL was studied in N-formylation of amines under solvent-free grinding condition. The methodology provided cleaner conversion over shorter reaction time with high turnover frequency (TOF) and chemoselectivity. (C) 2014 Elsevier B.V. All rights reserved.

C1, seen them all: A catalytic transformation that uses CO2 as an oxygen‐free C1 building block is presented. The reductive functionalization of CO2 is promoted by N‐heterocyclic carbenes or guanidines as organocatalysts in the presence of amines and hydrosilanes. This diagonal strategy selectively affords benzimidazoles, quinazolinones, 3,4‐dihydroquinazolines, formamidines, and their derivatives
