This review article focuses on amidinatotetrylenes that potentially can (or have already shown to) behave as bi- or tridentate ligands because they contain at least one amidinatotetrylene moiety (silylene, germylene stannylene) and more) additional coordinable fragment(s). Currently, are being widely used in coordination chemistry, small molecule activation catalysis. classifies those been isolated transition metal-free compounds into five families differ the position(s) of donor group(s) (D) moiety, namely: ED{R

Abstract Cobalt complexes featuring triazine‐based PNP ligands have proven to be exceptionally active and chemoselective pre‐catalysts in facilitating the dehydrogenative coupling between silanes amines, leading synthesis of diverse aminosilanes. Notably, even challenging substrates exhibited high reactivity. The catalyst‘s unique feature avoiding with tertiary enhances process chemoselectivity. It facilitates a more precise silylamines possessing SiH 2 −N SiH−N motifs, overcoming challenges associated broader reactivity seen previous systems. In terms its remarkable chemoselectivity, it is also noteworthy that catalytic system exhibits both versatility efficacy converting untouched double triple carbon‐carbon bonds. This accomplishment particularly significant, given brought about by activity commonly employed catalysts competitive hydrosilylation process.

The commercial reagent, HSi(OEt)3, was an efficient catalyst for the synthesis of E-alkenylboronate esters and alkyl gem-diboronate by single or double hydroboration terminal alkynes with HBPin (pinacolborane). reaction time controlled whether a addition to occurred. Aromatic containing strong electron-donating -withdrawing substituents at different positions as well aliphatic were efficiently mono- dihydroborated. Mechanistic studies suggested that formation diboronate proceeds second cycle being rate determining. HSi(OEt)3 has been identified deactivation pathway operative in catalysis. Screening other silicon compounds this transformation supported steric electronic profile is key promote step.
