The use of a boronic acid co-catalyst along with a palladium complex enables efficient dehydrative couplings of allylic alcohols and tautomerizable heterocycles. The protocol has been applied to achieve N-allylations of 2-pyridones, 4-pyridones, 4-pyrimidinones, and their benzofused derivatives.

A process for preparing 2-fluoro-1-olefins or terminal bis-beta-fluoro-olefins which comprises reacting an appropriate allyl or alpha-olefinated starting material with phenylselenyl chloride and silver fluoride, and then reacting the intermediate phenylselenyl fluoride compound with ozone, and further reacting the resulting phenylselenoxide compound with an appropriate amine, to yield the desired fluorinated compounds.
