The prototypical catalytic reductiveC–Cbond formations, the Fischer-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 homogeneous 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 field of research lay fallow for several decades. Eventually, the increased availability of mild terminal reductants, in particular silanes, led to a renaissance in the area of catalytic reductive C–C bond formation. For example, the first catalytic reductive C–C couplings beyond hydroformylation, which involve the hydrosilylative dimerization of conjugated dienes [6–12], appeared in 1969 – approximately 16 years after the first reported metal-catalyzed alkene hydrosilylation [13]. Following these seminal studies, the field of catalytic reductive C–C bond formation underwent explosive growth, culminating in the emergence of an ever growing body of research encompassing a powerful set of transformations.
