Application
Potassium (2Z)-2-buten-2-yltrifluoroborate can be used as a substrate:
- In the asymmetric alkenylation of imines/aldimines using a rhodium based catalyst.
- In the Rh(I)-catalyzed allylic amines synthesis by reacting with N-tert-butanesulfinyl aldimines.
- In the ytterbium triflate catalyzed multicomponent synthesis of β-unsaturated α-amino esters.
