Description

Application

Potassium trans-1-propenyltrifluoroborate can be used:

• As a substrate in the cross-coupling reactions with 2-(chloromethyl)-2,1-borazaronaphthalenes to yield allyl borazaronaphthalenes using a palladium catalyst.
• In the synthesis of anethole dithiolethione-NH₂ (ADT-NH₂), which in turn is used to prepare a drug-H₂S delivery system.
• To prepare methyl (E)-2,2-dimethyl-5-(propen-1-yl)-4H-benzo[d][1,3]dioxine-7-carboxylate, a key intermediate for the synthesis of the alkaloid ampullosine.
