So glad to share our revision article is available as Advance Article at Chem. Soc. Rev.
We are starting 2020-2021 academic course and we have good news... our revision publication at Chemical Society Revies journal, entitled "Catalytic addition of C–H bonds across C–C unsaturated systems promoted by iridium(i) and its group IX congeners" and authored by D. Fernández, J. L. Mascareñas and F. López is already on-line.
Abstract: Transition metal-catalyzed hydrocarbonations of unsaturated substrates
have emerged as powerful synthetic tools for increasing molecular
complexity in an atom-economical manner. Although this field was
traditionally dominated by low valent rhodium and ruthenium catalysts,
in recent years, there have been many reports based on the use of
iridium complexes. In many cases, these reactions have a different
course from those of their rhodium homologs, and even allow performing
otherwise inviable transformations. In this review we aim to provide an
informative journey, from the early pioneering examples in the field,
most of them based on other metals than iridium, to the most recent
transformations catalyzed by designed Ir(I) complexes. The review is organized by the type of C–H bond that is activated (with C sp2, sp or sp3),
as well as by the C–C unsaturated partner that is used as a
hydrocarbonation partner (alkyne, allene or alkene). Importantly, we
discuss the mechanistic foundations of the methods highlighting the
differences from those previously proposed for processes catalyzed by
related metals, particularly those of the same group (Co and Rh).
