An Improved Synthesis and Isolation of Tribenzylbismuth

Abstract

A much improved synthesis and isolation of tribenzylbismuth (Bn₃Bi where Bn = CH ₂ C ₆ H ₅ ) compared to the previous literature preparation is presented. Using the described method, a ≥ 3-fold increase in yield of analytically pure compound is obtained, providing Bn ₃ Bi in synthetically useful quantities. Additionally, full spectral characterization has been achieved ( ¹ H and ¹³ C NMR, IR) for the first time. Thermal analysis was performed via condensed phase pyrolysis and differential scanning calorimetry (DSC). The DSC data was used to estimate Δ H _f (Bn ₃ Bi) _liquid .
