Novel class of diboron reagent boronyl borinic ester was developed that were generated as B2pin2/secBuLi/TFAA adducts. Detailed NMR with solid-state 2D NMR techniques and ESI-MS investigations were used to get structural insights of these new reagent. The new boronyl borinic esters were proved to be promising for allylic borylations of base-sensitive substrates.
