Abstract A bifunctional metal organic framework catalyst containing palladium and copper(II) benzene‐1,3,5‐tricarboxylate – MOF‐Cu(BTC)‐[Pd] has been prepared. This enables the performance of tandem Sonogashira/click reaction starting from 2‐iodobenzylbromide, sodium azide alkynes to produce 8 H ‐[1,2,3]triazolo[5,1‐ a ]isoindoles with good yields under mild conditions.
Biscarbene ligands with two imidazolin-2-ylidene moieties at a chiral dioxolane backbone were used as for gold, rhodium and palladium complexes. All new complexes showed varying degrees of enantioselectivity toward hydrogenation prochiral alkenes ees up to 95%.
We present the successfully synthesis of a series chiral polymeric aromatic frameworks containing novel enantiopure atropoisomeric 1,1′-binaphthyl-dihydroazepine-based compounds as structural building units named cBAPAFs. Three porous materials with amino, pyridinic and amino-alcohol functionalities were obtained from dibrominated monomers by Suzuki-Miyaura couplings. New surface areas up to 619 m2 g−1 determined Brunauer–Emmett–Teller (BET), high thermal stability. The use nitrogen-based...
The enantioselective discrimination of racemic compounds can be achieved through the design and preparation a new family chiral conjugated BINOL–porous polymers (CBPPs) from enantiopure (R)- or (S)-BINOL derivatives 1,3,5-tris(4-phenylboronic acid)benzene 1,3,5-tris(4-ethynylphenyl)benzene, 1,3,5-triethynyl-2,4,6-trifluorobenzene, tetra(4-ethynylphenyl)methane as comonomers following Suzuki–Miyaura Sonogashira–Hagihara carbon–carbon coupling approaches. obtained CBPPs show high thermal...
Chiral compounds prepared from proton sponge building block 8-((2R,5R)-2,5-dimethylpyrrolidin-1-yl)naphthalen-1-amine were found to be effective chiral ligands for obtaining complexes of rhodium(I) and palladium(II) by reaction with [RhCl(cod)]2, PdCl2(cod) or Pd(OAc)2. The bearing triethoxysilane groups immobilized on mesoporous MCM-41 in order obtain new heterogeneous catalysts. Both materials are active the hydrogenation alkenes could recycled without loss activity enantioselectivity.
