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.
