Abstract: Heterogeneously catalyzed racemization reactions of the secondary amines (S)‐1‐methyl‐6,7‐dimethoxy‐1,2,3,4‐tetrahydroisoquinoline (salsolidine) and (S)‐1‐methyl‐1,2,3,4‐tetrahydro‐ß‐carboline were investigated using Pd, Pt, and Ir on carbon or Al2O3 supports. A comparison of kinetics and deactivation on selected platinum and iridium… read more here.

Abstract: By adding 4,4′-bipyridine (BPY) to cross-link the paddle-wheel clusters M2(–COO)4L2, isoreticular metal–organic frameworks (MOFs) have been constructed from a flexible tritopic linker, 4,4′,4′′-s-triazine-1,3,5-triyltri-p-aminobenzoic acid (H3TATAB), termed as ST-14 [Cu6(TATAB)4(BPY)3] and ST-15 [Zn6(TATAB)4(BPY)3]. With a secondary-amine… read more here.
