文摘
- •
A novel class supramolecular pillar[5]arene-NHC ligands were prepared.
- •
The NHC ligand 3b demonstrated has good catalytic activity in Heck reaction.
- •
The steric bulk of the ligand seems to have much impact on the Heck coupling.
- •
Pillararene as catalyst is just started, we are pursuing more efficient catalyst.
