“…L. Micouin et al [62] proposed alternative routes for direct access to 3,4,5-trisubstituted isoxazoles and 1,3,4,5-tetrasubstituted pyrazoles (Scheme 25). Structurally simple precursors have been obtained as aluminum heterocyclic compounds by metal cyclization in a fully chemical and regioselective manner.…”

This review highlights recent advances in the research of organoaluminum complexes in catalysis. Many fundamental transformations can be carried out by aluminum catalysts, such as hydroboration, hydroamination, copolymerization and CO 2 insertion reactions, hydrosilylation, and hydroacetylenation of carbodiimides, which make use of the abundant reserves of aluminum in the earth's crust to accomplish the transformation. Recent research in the field has shown that these systems have extraordinary catalytic activity and are inexpensive, abundant, and environmentally friendly.

“…As such, organolanthanides and early actinides form catalytically active Ln−H and An−H species. 209,210 The catalytic activities of f-block metal complexes are significantly influenced by the nature of the metal center and the steric and electronic nature of the ligand. Thus, for f-block metal-catalyzed hydroelementations, larger metal ions bearing a less sterically hindered coordination sphere show higher activity.…”

s-Block Metal Catalysts for the Hydroboration of Unsaturated Bonds

The addition of a B–H bond to an unsaturated bond (polarized or unpolarized) is a powerful and atom-economic tool for the synthesis of organoboranes. In recent years, s-block organometallics have appeared as alternative catalysts to transition-metal complexes, which traditionally catalyze the hydroboration of unsaturated bonds. Because of the recent and rapid development in the field of hydroboration of unsaturated bonds catalyzed by alkali (Li, Na, K) and alkaline earth (Mg, Ca, Sr, Ba) metals, we provide a detailed and updated comprehensive review that covers the synthesis, reactivity, and application of s-block metal catalysts in the hydroboration of polarized as well as unsaturated carbon–carbon bonds. Moreover, we describe the main reaction mechanisms, providing valuable insight into the reactivity of the s-block metal catalysts. Finally, we compare these s-block metal complexes with other redox-neutral catalytic systems based on p-block metals including aluminum complexes and f-block metal complexes of lanthanides and early actinides. In this review, we aim to provide a comprehensive, authoritative, and critical assessment of the state of the art within this highly interesting research area.

“…Over the last 5 years, many articles in this field have appeared, and the conducted research has allowed the creation of a database of effective complexes, which are a combination of a metal and a specially designed ligand. A few reviews were published in 2018–2019 in which the general (asymmetric) hydrofunctionalization of alkenes and alkynes catalyzed by earth-abundant metals ,,,− and lanthanide and actinide complexes was discussed. An excellent review recently presented complexes of elements from the first row of d-block as catalysts for the formation of a carbon–boron bond .…”

While the formation and breaking of transition metal (TM)–carbon bonds plays a pivotal role in the catalysis of organic compounds, the reactivity of inorganometallic species, that is, those involving the transition metal (TM)–metalloid (E) bond, is of key importance in most conversions of metalloid derivatives catalyzed by TM complexes. This Review presents the background of inorganometallic catalysis and its development over the last 15 years. The results of mechanistic studies presented in the Review are related to the occurrence of TM–E and TM–H compounds as reactive intermediates in the catalytic transformations of selected metalloids (E = B, Si, Ge, Sn, As, Sb, or Te). The Review illustrates the significance of inorganometallics in catalysis of the following processes: addition of metalloid–hydrogen and metalloid–metalloid bonds to unsaturated compounds; activation and functionalization of C–H bonds and C–X bonds with hydrometalloids and bismetalloids; activation and functionalization of C–H bonds with vinylmetalloids, metalloid halides, and sulfonates; and dehydrocoupling of hydrometalloids. This first Review on inorganometallic catalysis sums up the developments in the catalytic methods for the synthesis of organometalloid compounds and their applications in advanced organic synthesis as a part of tandem reactions.
