Competitive chlorination of p-substituted triarylbismuthanes 1 [(p-XC6H4)3Bi; a: X = OMe, c: Cl, d: CO2Et, e: CF3, f: CN, g: NO2] and trimesitylbismuthane (2,4,6-Me3C6H2)3Bi 1h by sulfuryl chloride was carried out against 1b (X = H) and the effect of these substituents on the formation of triarylbismuth dichlorides 2 was studied. The relative ratios 2/2b decreased with increasing electron-withdrawing

A series of Antimony(III) and Bismuth(III) pnictogen bonding (PnB) triaryl-based anion receptors demonstrate PnB anion binding strength is influenced strongly by the electronic withdrawing nature of the aryl substituent and pnictogen atom donor identity. The triaryl PnB receptors display chloride anion selectivity over a range of halides and oxoanions. The synthesis and preliminary chloride anion binding
