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.

The BF(3)·OEt(2)-mediated allylation of isatin with an α-chiral allylic stannane is diastereo- and enantioselective. Conversely, allylation of any substituted isatin employing the identical protocol is not diastereoselective at all and only enantioselective for the major diastereomer having syn relative configuration.
