Baltus, Christine B. published the artcileMicrowave-mediated Suzuki-Miyaura cross-couplings of thioether- and ortho-substituted methylphenylboronic acid esters, SDS of cas: 1012785-48-6, the publication is Synlett (2012), 23(17), 2477-2480, database is CAplus.
Hiterto unsuccessful cross-couplings of ortho-substituted or thioether-substituted methylphenylboronates have now been achieved, under microwave conditions, enabling the synthesis of a library of novel biaryls. Tetrakis(triphenylphosphine)palladium and various bases, for example, sodium carbonate or cesium fluoride, were found to mediate the crucial C-C bond-forming cross-coupling reaction. E.g., in presence of tetrakis(triphenylphosphine)palladium and CsF, reaction of thioether-substituted methylphenylboronate (I) and 4-BrC6H4NO2 gave 91% II.
Synlett published new progress about 1012785-48-6. 1012785-48-6 belongs to piperazines, auxiliary class Boronic acid and ester, name is tert-Butyl 4-(2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl)piperazine-1-carboxylate, and the molecular formula is C22H35BN2O4, SDS of cas: 1012785-48-6.
