Reaction of the pincer-type ligand L3 supported complex [L3PbBr][BArF24] (1) with Li[(C(=N2)TMS)] furnishes [L3Pb(C(=N2)TMS)][BArF24] (2). Diazo-compound 2 eliminates dinitrogen upon irradiation affording formal plumba-alkyne 3, which persists in cold fluoroarene solutions. Variable temperature UV/Vis and NMR spectroscopies combination quantum-chemical calculations identify 3 as a metal-substituted triplet carbene. In-crystallo [L3Pb(C(=N2)TMS)(tol)][BArF24] (2∙tol) provides snapshot intermolecular C–H bond insertion toluene (4).

The stabilization of simple, highly reactive cationic species in molecular complexes represents an important strategy to isolate and characterize compounds with uncommon or even unprecedented structural motifs properties. Here we report the synthesis, isolation, full characterization chlorido-bismuth dications, stabilized only by monodentate dimethylsulfoxide (dmso) ligands: [BiCl(dmso)

Abstract Establishing unprecedented types of bonding interactions is one the fundamental challenges in synthetic chemistry, paving way to new (electronic) structures, physicochemical properties, and reactivity. In this context, unsupported element‐element are particularly noteworthy since they offer pristine scientific information about newly identified structural motif. Here we report synthesis, isolation, full characterization heterobimetallic Bi/Pt compound [Pt(PCy 3 ) 2 (BiMe )(SbF 6 )] ( 1 ), bearing first transition metal→bismuth donor/acceptor interaction as its key surprisingly robust, electronic spectra interpreted a fully relativistic approach, it reveals an reactivity towards H .

Main group elements have recently emerged as benign and cost-effective alternatives to transition metals in organometallic chemistry. By finely tuning their electronic structure, these can engage substrate coordination, activate small molecules, even catalyse redox reactions, mirroring the behaviour of metals. This book chapter aims summarize a relatively underexplored area within main metal chemistry: ability undergo photoinduced processes such reactivity, rearrangements, radical formation.
