“…This may suggest that the role of NaH is at least in part similar to that of Zn 0 , a reductant, and that they reinforce each other. This is supported by Caubère’s work on NiCRA56-63 (See Section 2.2.1), where NaH mediated hydridic reduction of Ni II species was shown to be a contributing reaction. Regardless of the mechanism of this transformation, a variety of α-iodo-α, β-unsaturated ketones, as well as 2-bromopyridine, α-bromostyrene, and β-bromostyrene were compatible with this catalytic system.…”
