Oxidation of alcohols with 1-decyl-4-aza-1-azonia-bicyclo[2.2.2]-octane chlorochromate under conventional and solvent-free conditions

WITHDRAWN: Silica-supported N-alkyl DABCO incorporating different anions: efficient heterogeneous catalysts for the transformation of epoxides to cyclic carbonates

“…[31][32][33] The presence of the organic groups in these immobilized catalysts was confirmed by FT-IR, titrimetric analysis (TA), elemental analysis (EA), inductively coupled plasma analysis (ICP), and TGA-DTA techniques.…”
