A radical partner turns a cheap manganese catalyst into a water splitter, and reveals how Photosystem II may pull off the same trick.

Reactions of LiPR2 with BiCl3 selectively give diphosphanes R2P–PR2 in high yields, presumably via Bi─P homolysis. This includes challenging cases with bulky substituents R. Sterically encumbered dip....

We report the synthesis of three chloropnictogenium cations [MSFluindECl]+ (2As, 2Sb and 2 Bi), which unravel different reaction pathways toward Et3SiH, leading to the formation of the neutral arylars...

Molecular complexes of iron in the rare +1 oxidation state have been shown to be efficient catalysts for industrially relevant chemical transformations, typically associated with the increasingly unsu...

Cyclic peroxides are highly reactive oxygen-containing species that play important roles in chemical synthesis. Now, the reaction between diazoboranes and triplet oxygen affords a family of cyclic dio...

Der Würzburger Chemieprofessor Frank Würthner erhält die höchste internationale Auszeichnung, die es im Bereich der supramolekularen Chemie gibt, den Izatt-Christensen Award.

Peter Coburger and Stefan Frei, Germany, discusses assembling highly tunable, strongly π-donating zwitterionic diphosphacyclobutadienyl ligands directly within Mn and Co complexes

A modular synthetic approach affords a series of cationic cobalt and manganese carbonyl half-sandwich complexes bearing onium-substituted diphosphacyclobutadienyl ligands. In this strategy, the onium....

Sandwich compounds are foundational to organometallic chemistry, yet carbon-free analogs remain exceptionally rare. We report the all-phosphorus heteroleptic cobalt sandwich anion [(η5-P5)Co(η3-P3)]− ...

Rare examples of alkyl bismuth cations [BiR2(SbF6)] are presented, including cyclopropyl ligands and a bismacyclic structure. The bismuth-centered Lewis acids act as Z-type ligands toward the electro....

Here, we report a breakthrough study in catalytic alkene isomerisation using crown ether-supported alkali metal phosphides in which the activity increases sequentially and significantly as Group One ...

Reactions of three aryl-substituted bismuth cations, [BiPh2(SbF6)], [BiMes2(SbF6)], and [BiDipp2(SbF6)], with the Pt0 complex Pt(PCy3)2 have been investigated (Mes = 2,4,6-trimethyl-phenyl; Dipp = 2,6-di-iso-propyl-phenyl; Cy = cyclohexyl). Unexpectedly, and in contrast with the reactivity of the recently reported methyl analogue [BiMe2(SbF6)], the formation of isolable metal-only Lewis pairs [(Cy3P)2Pt→BiAr2(SbF6)] is not observed (Ar = aryl). Instead, an unprecedented bismuth-to-platinum oxidative aryl transfer is witnessed to give the PtII complexes [PtAr(PCy3)2(SbF6)], along with the suggested bismuthinidene intermediates BiAr. Attempts to trap these fleeting intermediates with an ortho-quinone led to a PtII semiquinone radical complex.

We report the transition-metal-like reactivity of a geometrically constrained, ambiphilic bismuth(III) trisamide. Planarization of the Bi(III) center unlocks Bi–C bond formation when reacted with mild...

The first series of fully characterized homoleptic alkynyl bismuth compounds Bi(C≡CR)3 is presented. Facile homolytic Bi–C bond cleavage grants access to alkynyl radicals, which have been employed in...

Carbon monoxide (CO) is one of the simplest and most fundamental molecules that has fascinated chemists for decades. Early-on, chemists have recognized and exploited its favorable properties as a key ...

The simplistic methylbismuth dication has been captured only by the aid of monodentate tetrahydrofuran (thf) ligands, [BiMe(thf)5]2+. The hexacoordinate species shows a very unusual pentagonal pyrami...

Inspired by and honouring place, we are a community-minded, globally engaged university where we transform ideas into meaningful impact.

This article reports on the isolation of a monomeric compound with a dianionic singly reduced bis(pyridylimino) isoindolide (BPI) ligand and elaborated discussions on the structure of reduced BPIs.

We describe the reaction between the linear iron(I/II) silylamides [FeL2]0,– (L = N{Dipp}SiMe3) and aryl azides N3R with different steric demand (R = Ph, 2-Me-C6H4 (Tol), 2,4-Me2-C6H3 (Xyl), 2,6-iPr2-...
