Abstrakt: A much improved synthesis and isolation of tribenzylbismuth (Bn3Bi where Bn = CH2C6H5) 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 Bn3Bi in synthetically useful quantities. Additionally, full spectral characterization has been achieved (1H and 13C 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 Hf(Bn3Bi)liquid. [ABSTRACT FROM AUTHOR]
