Phenyl bismuth β-diketonate complexes: Synthesis and structural characterization

“…The XRPD study of the residue resulted upon thermal decomposition of 1 in Ar probed the formation of a complex mixture with BiOF being a major phase. The formation of BiOF upon thermal treatment of fluorine-containing bismuth(III) compounds has been previously reported in the literature [12,13]. The thermal decomposition of the adducts 1a-1f somewhat mirrors what was observed for the thermolysis of 1.…”

A Redox‐Confused Bismuth(I/III) Triamide with a T‐Shaped Planar Ground State

“…Zuschriften more typical of electrophilic Bi III compounds (Scheme 3). Reaction of 2 with pentafluorophenol showed complete loss of the blue color and conversion into N 3 H 3 and the known compound Bi(OC 6 F 5 ) 3 [20] at all stoichiometries,i ndicating ametathesis reaction that is well-known for Bi III triamides. [21] Similarly,the mixture of 2 and PCl 3 gave 3 under elimination of BiCl 3 (Scheme 3).…”

“…[12a,b] In sharp contrast with these intensely colored bismuthinidenes,p yramidal Bi III triamides are generally colorless to pale yellow [19] as are planar boron(III) analogues of 2. [15a] Collectively,t hese features suggest that 2 is aB i I compound in the solid, solution, and gas phases,made accessible in the absence of external reductants by partial oxidation of the tridentate ligand as per Scheme 1b.I ti si nteresting therefore that as urvey of its reactivity revealed behavior Reaction of 2 with pentafluorophenol showed complete loss of the blue color and conversion into N 3 H 3 and the known compound Bi(OC 6 F 5 ) 3 [20] at all stoichiometries,i ndicating ametathesis reaction that is well-known for Bi III triamides.

Creating Iron– and Rhenium–Bismuth Bonds by Reactions with Organometallic Hydrides

“…To avoid exhaustive exchange of alkoxide ligands by the strong nucleophile [Fp] – we then employed a less reactive alkoxide with different solubility characteristics. Electron‐withdrawing trifluoromethyl groups as part of the alkoxide ligands in dimeric [Bi{OCH(CF 3 ) 2 } 3 (thf)] 2 , have been shown to deactivate the bismuth alkoxide for the alcohol elimination reaction in previous work, where [(Cp 2 Re) 2 Bi{OCH(CF 3 ) 2 }] could be isolated but not its close derivative [(Cp 2 Re) 2 Bi(O t Bu)] ( II ) due to subsequent C–H activation reactions and elimination of t BuOH in the latter case which led to the precipitation of [CpRe( μ ‐ η 5 , η 1 ‐C 5 H 4 )Bi–ReCp 2 ] ( III ) , …”
