Abstract Two homologous series of pnictogen(III) dications, stabilized by 2,6‐bis(benzimidazole‐2‐yl)pyridine ligands have been prepared. Both contain Pn III ‐X moieties (Pn = P, As, Sb, Bi; X Cl or Ph) and fully characterized using spectroscopic methods including X‐ray crystallography. The Lewis acidity these compounds has also probed computational methods; the results suggest that dictations are strong acids, with PnCl 2+ being more acidic than PnPh compounds, increasing from P to Bi, in both series. PhP ‐containing compound was found be a versatile transfer reagent, leading new synthetic routes for various PhP‐containing compounds. redox chemistry all cyclic voltammetry chemical reductions.

Bulky NCN aryl-diamides featuring methyl groups in the benzyl positions were synthesized with aim of creating a new class meta-xylene-based trianionic pincer ligands where common decomposition pathway metal complexes via C-H activation is prevented. Sterically demanding substituents on furthermore provide steric protection centre and can help prevent dimerization complexes. While double deprotonation formation dilithium salt was straightforward, difficulties encountered when attempting to deprotonate ipso-CH proton central aryl ring yield ligands. This stands contrast related without benzylic positions. Experimental theoretical investigations led conclusion that challenges third are likely caused by an interplay increased electron density at nitrogen atoms hindrance. Both effects originate introduction positions, which make targeted less accessible. These results further insight into impact both electronic properties ligands, may find utility coordination chemistry applications metalation be achieved direct rather than requiring triple deprotonation.
