when 6 (in large excess) is introduced, the equilibria are driven
to favoring the formation of 14.
Based on the studies above and the literature, a proposed
mechanism for the alkylation, exemplified by that of 5 with 6, is
shown in Scheme 5. The activation of 3 in toluene with NaBHEt3
results in the formation of a complex mixture, which is converted
into the complex 14 upon introducing 6, with 14 in equilibrium
with 12. Protonation of the latter with 5 affords 15, from which -

benzaldehyde while generating 11a.[11c,
The benzaldehyde
condenses with 6 with the aid of a base to produce the olefin
intermediate 10, which is reduced by 11a to give the alkylated
product 7a, while regenerating 12. The species involved in the
catalytic cycle are probably in equilibrium with each other via
dissociation/association of substrates, aldehydes and H2. As
mentioned, the catalysis appears to be rate-limited by the step of
hydrogenation of 10. This remains, however, largely hypothetic,
without measuring the rate constants and/or calculating the
energy barriers of catalytic cycle.

In summary, the first Fe catalyzed α-alkylation of nitriles with
primary alcohols via a hydrogen borrowing pathway has been
developed. The catalytic system shows broad substrate scope
and high activity. Mechanistic studies showed that the reaction
proceeds sequentially, involving the intermediary of an olefin.
Significantly, the commonly adopted procedure of catalyst
activation with boron hydrides leads to a complex mixture of iron
species, and it is the nitrile substrate that converts these species
into an active hydride catalyst.
