Allylation of aldehydes with potassium allyltrifluoroborate catalyzed by Amberlyst A-15
Tetrahedron, 2013Abstract The use of the commercially available resin Amberlyst-15 as catalyst for allylation of aldehydes by potassium allyltrifluoroborate is described. The method features the use of a commercially available catalyst, aqueous media, and the products were obtained in high yields, short reaction times, at room temperature and no further purification.

The double allylboration of nitriles and acid anhydrides to form bis-allyl amines and esters, respectively, can be achieved through the use of potassium allyltrifluoroborate in the presence of boron trifluoride etherate at room temperature. The method described is relatively mild, exhibits chemoselectivity to other electrophiles present, avoids the use

A practical method for the chemo- and diastereoselective allylation of α,β-epoxy ketones has been developed by using the convenient air and moisture stable reagent potassium allyltrifluoroborate. Indium metal was found to promote addition in stoichiometric or catalytic amounts, to afford α,β-epoxyhomoallylic tertiary alcohols in high yields and ...

Synthesis of allyl sulfones from potassium allyltrifluoroborates
Tetrahedron Letters, 2017Abstract Potassium allyltrifluoroborates underwent a bora-ene reaction with sulfur dioxide in the absence of Lewis acid catalysts to give sulfinyloxy-trifluoroborates, which subsequently undergo alkylation with electrophiles to produce sulfones in up to 91% yield.
