General description

Boron trifluoride diethyl etherate or boron trifluoride-ether complex is an organic compound widely used as a convenient source of boron trifluoride (BF3) in organic synthesis. It is also used as a Lewis acid for the activation of electrophiles.

Application

Catalyst used in the preparation of cyclopentyl- and cycloheptyl[b]indoles from aryl cyclopropyl ketones via [3+2] cycloaddition.
Lewis acid reagent with broad application

Packaging

The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

An easy and straightforward synthesis of 6,10b-diarylhexahydrobenzo[f]isoquinoline by the repeated treatment of boron trifluoride etherate (BF(3) x OEt(2)) is reported. The overall transformation from 4-arylpiperidin-3-one to benzo[f]isoquinoline proceeds via ring contraction, chain elongation, and intramolecular electrophilic cyclization in moderate yields.
