Abstract
Boron triiodide (BI3) is a versatile reagent with underexplored chemical utility. Major factors that affect its lack of use are the expensive cost and dark, moisture free storage requirements. Despite this, BI3 can be synthesized using relatively inexpensive potassium borohydride (KBH4) and molecular iodine (I2). However, prior literature on BI3 generation often make use of impractical experimental setups, including ambiguous experimental details, and report varying yields for similar or identical protocols. To enable continued investigation of the unique chemical behavior of BI3, a streamlined production method that is accessible, reproducible, and gram-scale is highly desirable. Herein, we report a one-pot gram scale generation of BI3. Characterization and purity were evaluated by PXRD, NMR, IR, and UV/Vis spectroscopy, as well as melting point assessment. Furthermore, the experimental design addresses potential safety risks while simplifying the reaction setup to a modular all-in-one system that is suitable for the typical research laboratory.
