Group 5 Imides and Bis(imide)s as Selective Hydrogenation Catalysts

Abstract: In this microreview, we focus on our work on the development of group 5 imido and bis(imido) semihydrogenation catalysts in the context of previous stoichiometric studies on d0 metal–ligand multiple‐bond activations of strong σ bonds and both stoichiometric and catalytic studies on H2 activation and hydrogenation by d2 group 5 complexes. These studies develop electronic structure models and mechanistic analyses necessary for the application of catalytic reactions involving 1,2‐addition reactions of σ‐bonded su… Show more

“…Additionally, there are very few examples of direct H 2 activation by d 2 group 5 metals 160166 . Nonetheless, there are several elegant examples of arene and alkene hydrogenation and alkyne semi-hydrogenation catalysed by d 2 group 5 metals 162,167178 .…”

“…8 In the realm of related group 4 terminal chalcogenide complexes, [47][48][49][50][51][52][53] a handful of Ti and Zr oxo and suldo complexes were shown to react stoichiometrically with dihydrogen and silanes via a 1,2-addition pathway. [54][55][56] In contrast, while many examples of group 5 mono(imido) and mono(oxo) complexes have been reported, [57][58][59][60][61][62][63][64] only a few have been shown to exhibit 1,2-addition reactivity, 8,43,65,66 suggesting that these systems could benet from activation of metal-ligand multiple bonds via a p-loading strategy.…”

“…Metal imido moieties are synthesized in a variety of ways1 and play key roles in many organometallic processes, including olefin polymerization,2 alkyne hydrogenation,3 azide hydrogenation,4, 5 CH bond activation,6 and group‐transfer processes 4. 7 Although low‐valent mono(imido) species have been heavily studied, relatively little is known about more oxidized species bearing two or three imido substituents.…”
