allowed for the rapid determination of the most suitable ligand, specifically 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane, for facilitating Suzuki-type couplings of alkyl halides or tosylates containing β-hydrogens with either boronic acids or alkylboranes.
通过1,3,5,7-四甲基-2,4,8-三氧杂-6-磷酸金刚烷的P-芳基化反应制备了磷金刚烷配体的15元文库。对该叔膦收集物的筛选可以快速确定最合适的配体,特别是1,3,5,7-四甲基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷酸金刚烷,用于促进含β-氢的烷基卤或甲苯磺酸酯与硼酸或烷基硼烷的铃木型偶联。
