The palladium-catalyzed cross-coupling of (E)-2-fluoroallyl carbonates and allylboronates is reported. The regioselectivity is susceptive to the steric requirements of the NHC ligand, with small IMes favoring the linear fluorinated 1,5-dienes, while the IPrBIDEA featuring sterically-congested character benefits the branched products. Control experiments revealed that either 2-fluoroallyl carbonates or gem-F2CPs could undergo allylation with excellent regioselectivity, yet the former behaved with some lower branched reactivity.
