Bis(pinacolato)diboron(L-Threonyl-L-histidyl-L-threonyl-L-asparaginyl-L-isoleucyl-L-seryl-L-alpha-glutamyl-L-seryl-L-histidyl-L-prolyl-L-asparaginyl-L-alanyl-L-threonyl-L-phenylalanine，C66H98N20O24) appears as powder or platelets. Bis(pinacolato)diboron is soluble in tetrahydrofuran, dichloromethane, toluene, hexane and heptane and insoluble in water. | [Uses]
Bis(pinacolato)diboron is used as a condensation agent in the preparation poly(arylene)s. It is an organoboranate with potential use as matrix metallo-proteinase (MMP-2) inhibitor. | [Definition]
ChEBI: Bis(pinacolato)diboron is a 1,3,2-dioxaborolane that is 4,4,5,5-tetramethyl-1,3,2-dioxaborolane in which the boron hydrogen at position 2 is replaced by a 4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl group. It is a reagent used in organic synthesis to synthesise pinacol boronic esters. It has a role as an EC 3.4.24.24 (gelatinase A) inhibitor. | [General Description]
Bis(pinacolato)diboron or (B2pin2) is the most commonly used diborane reagent in organic synthesis due to its high stability in air and moisture. It can be synthesized by treating tetrakis(dimethylamino)diboron with pinacol in acidic conditions. |
