TheprototypicalcatalyticreductiveC-Cbondformations,theFischer-Tropsch
reaction [1] and alkene hydroformylation [2], were discovered in
1922 and 1938, respectively [3,4]. These processes, which involve
reductive coupling to carbon monoxide, have long been applied to
the industrial manufacture of commodity chemicals [5]. Notably,
alkene hydroformylation, also known as the oxo-synthesis, has
emerged as the largest volume application of homo- neous metal
catalysis, accounting for the production of over 7 million metric
tons of aldehyde annually. Despite the impact of these prototypical
reductive C-C bond formations, this ?eld of research lay fallow for
several decades. Eventually, the increased availability of mild
terminal reductants, in part- ular silanes, led to a renaissance in
the area of catalytic reductive C-C bond
formation.Forexample,the?rstcatalyticreductiveC-Ccouplingsbeyond-
droformylation, which involve the hydrosilylative dimerization of
conjugated dienes [6-12], appeared in 1969 - approximately 16 years
after the ?rst - ported metal-catalyzed alkene hydrosilylation
[13]. Following these seminal studies, the ?eld of catalytic
reductive C-C bond formation underwent exp-
sivegrowth,culminatingintheemergenceofanevergrowingbodyofresearch
encompassing a powerful set of transformations. To our knowledge,
no thematic volumes devoted solely to metal-catalyzed reductive C-C
bond formationhave been assembled. For the ?rst time, in this issue
of Topics in Current Chemistry,wepresent acompilation ofmonographs
from several leaders in this burgeoning area of research. This
collection of reviews serves to capture the diversity of catalytic
reductive C-C couplings presently available and, in turn, the
remarkable range of reactivity embodied by such transformations.
