Taw qhia thiab daim ntawv thov CAS 13675-18-8|TETRAHYDROXYDIBORON
Tetrahydroxydiboron feem ntau yog siv los ua cov tshuaj intermediates hauv Suzuki coupling. Qhov ntxov tshaj synthesis ntawm tetrahydroxydiboron tuaj yeem taug qab rov qab mus rau xyoo 1955. Wartik siv ntxig zinc electrode rau hauv cov kua boron trichloride los tsim tetrahydroxydiboron, uas tom qab ntawd ua rau cov dej ua ntej tsim tetrahydroxydiboron, thiab tom qab ntawd rhaub rau 220 degree rau lub cev qhuav dej. tsim (BO) X; Xyoo 1961, McCloskey tau siv ib txoj hauv kev ntxiv kom muaj nuj nqis hydrochloric acid dropwise rau kev sib xyaw ntawm tetra (dimethylamino) diboron thiab dej ntawm 0 degree los tsim tetrahydroxydiboron hauv cov txiaj ntsig ntawm 56%. Nyob rau hauv ze li tsib caug xyoo tom ntej no, yuav luag tsis muaj pej xeem txoj kev qhia nyob rau hauv cov ntaub ntawv, mus txog rau thaum Molander ib zaug dua hais txog kev siv cov txheej txheem tom kawg los synthesize tetrahydroxydiboron nyob rau hauv 2012.
