Palladium-catalysed cross coupling of perfluoroalkenyl zinc reagents with 5-halo-6-azauracils
Abstract
The title reactions of 1,3-dimethyl-5-halo-6-azauracils with perfluoroalkenylzinc reagents [CF2=CFZnI and CF3C(ZnBr)=CF2] give not only corresponding alkenes but also, unexpectedly, a hexafluoroalkane derivative.
