What cross-coupling reactions can I use Ethylboronic acid in?
Ethylboronic acid is primarily used in Suzuki–Miyaura cross-coupling reactions with aryl or vinyl halides under palladium catalysis. This reaction forms C–C bonds with excellent functional group tolerance and mild conditions. It can also be used in Chan–Lam coupling for C–N and C–O bond formation without transition metal catalysts under aerobic conditions.
How should I store Ethylboronic acid?
Store in a tightly sealed container at room temperature under dry conditions. Protect from prolonged moisture exposure. Always consult the compound-specific Safety Data Sheet (SDS) provided with your order for detailed storage requirements. ChemContract Research includes handling and storage documentation with every shipment.
