文摘
- •
Synthesis of enantio pure (Tz)2Pd(I)2 with menthyl and neomenthyl wing-tip groups is reported.
- •
Synthesis of PEPPSI type (Tz)Pd(Py) (I)2 with menthyl and neomenthyl wing-tip groups is reported.
- •
Structural characterization by single crystal XRD is reported for all the complexes.
- •
Catalytic activities of all these complexes for Suzuki coupling were compared.
- •
Complexes with menthyl wing-tip group showed higher catalytic activities than the neomenthyl ones.
