Cas no 960-71-4 (Triphenylborane)

Triphenylborane (B(C6H5)3) is an organoboron compound widely used as a reagent in organic synthesis and catalysis. Its key advantages include its role as a Lewis acid, facilitating reactions such as hydroboration, polymerization, and cross-coupling processes. The compound exhibits high stability under standard conditions and demonstrates selectivity in activating substrates for C-C bond formation. Triphenylborane is also employed in the preparation of boron-containing materials and as a co-catalyst in olefin polymerization. Its well-defined reactivity and compatibility with various functional groups make it a valuable tool in both academic and industrial research settings. Proper handling under inert conditions is recommended due to its sensitivity to moisture and air.
