Use of a bulky phosphine of weak σ-donicity with palladium as a versatile and highly-active catalytic system: allylation and arylation coupling reactions at 10−1-10−4 mol% catalyst loadings of ferrocenyl bis(difurylphosphine)/Pd

A large range of palladium-catalysed C-N and C-C couplings (allylation and arylation, respectively) are achieved with a notable effectiveness using an easily accessible ferrocenyl bis(furylphosphine) in 10−1-10−4 mol% concentrations. These results shed a light on the use of the neglected bulky phosphines of low σ-donicity in suitable catalytic reactions, and herein in nucleophilic allylic substitution.
