The bis(allyl)bismuth cation: a reagent for direct allyl transfer by Lewis acid activation and controlled radical polymerization.
Lichtenberg C, Pan F, Spaniol TP, Englert U, Okuda J. Lichtenberg C, et al. Angew Chem Int Ed Engl. 2012 Dec 21;51(52):13011-5. doi: 10.1002/anie.201206782. Epub 2012 Nov 14. Angew Chem Int Ed Engl. 2012. PMID: 23166056
A positive effect: the bis(allyl)bismuth cation in [Bi(C(3)H(5))(2)(thf)(2)][B(C(6)H(3)Cl(2))(4)] is superior to neutral tris(allyl)bismuth in the additive-free allylation of unsaturated C-heteroatom functionalities and the controlled living radical polymerization o …

Lewis Superacidic Heavy Pnictaalkene Cations: Comparative Assessment of Carbodicarbene-Stibenium and Carbodicarbene-Bismuthenium Ions.
Warring LS, Walley JE, Dickie DA, Tiznado W, Pan S, Gilliard RJ Jr. Warring LS, et al. Inorg Chem. 2022 Nov 21;61(46):18640-18652. doi: 10.1021/acs.inorgchem.2c03135. Epub 2022 Nov 9. Inorg Chem. 2022. PMID: 36350227
Notably, [(CDC)SbBr][NTf(2)](2) (4) has an acceptor number (AN) (84) that is comparable to quintessential Lewis acids such as BF(3), and tricationic pnictaalkene complexes 11 and 13 exhibit strong Lewis acidity with ANs of 109 (Pn = Sb) and 84 (Pn = Bi), respectively, which are a …

Influence of pendant arms bearing ligating groups on the structure of bismuth porphyrins: implications for labeling immunoglobulins used in medical applications.
Halime Z, Michaudet L, Lachkar M, Brossier P, Boitrel B. Halime Z, et al. Bioconjug Chem. 2004 Nov-Dec;15(6):1193-200. doi: 10.1021/bc049844o. Bioconjug Chem. 2004. PMID: 15546184
For both types of complexes, the X-ray crystallography revealed that a single arm is actually in direct interaction with the bismuth cation, thereby allowing further functionalization on the porphyrin core as the linkage with immunoglobulins or anti-rabbit antibodie …
