Abstract:
The air-moisture stable and reusable multi-walled carbon nanotubes (MWCNTs) functionalized with a palladium(II)-Schiff base complex was synthesized by covalently anchoring a hydroxyl functionalized palladium(II)-Schiff base complex to modified MWCNTs. This heterogeneous catalyst exhibited effective catalytic activities by affording ynones in excellent yields from coupling reactions of acid chlorides with terminal alkynes under copper-, phosphorous- and solvent-free conditions in air.

Keywords:
Ynones
MWCNTs-Pd(II)-Schiff base
C C coupling
Terminal alkynes
Acyl chlorides
