Homoleptic bismuth phosphanides isolated! We are happy to share our recent findings @chemicalscience.rsc.org: pubs.rsc.org/en/content/a.... The title compounds readily release P-radicals, revealing a novel P-inversion pathway and P-radical transfer to external substrates. Congrats to the team!

Reactivity of Diaryl Bismuth Cations toward a Platinum(0) Complex: Oxidative Aryl Transfer 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.

#Bismuth meets platinum (#1): diaryl bismuth cations undergo oxidative aryl transfer to Pt(0)! Attempts to trap the low-valent Bi intermediate yielded a Pt radical complex. Now out in the p-block special issue of #Organometallics, @pubs.acs.org: pubs.acs.org/doi/10.1021/... Congrats to the team!

Ambiphilic Reactivity and Switchable Methyl Transfer at a T-Shaped Bi(NNN) Complex Enabled by a Redox-Active Pincer Ligand 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...

📣Our new paper is out in @jacs.acspublications.org (our very first one)!🥳

We show how a redox-active ligand unlocks C–X bond scission at an ambiphilic T-shaped Bi(III) compound. A big collaborative effort with my brilliant colleagues from Berlin.
