The invention relates to processes for the synthesis of aryl or alkene borates which comprises reacting: (i) an olefinic compound having a halogen or halogen-like substituent in a vinylic substitution position, or (ii) an aromatic ring having a halogen or halogen-like substituent in a ring substitution position, with a disubstituted monohydroborane in the presence of a Group 8-11 metal catalyst. The invention also relates to the use of these borates in coupling reactions. The invention further relates to certain disubstituted monohydroboranes and aryl or alkene borates.
该发明涉及合成芳基或烯烃硼酸酯的过程,包括以下反应:(i) 在烯烃化合物中的烯基取代位置具有卤素或类卤素取代基,或者(ii) 在芳香环中的环取代位置具有卤素或类卤素取代基,与二取代单氢硼烷在第8-11族金属催化剂存在下反应。该发明还涉及这些硼酸酯在偶联反应中的应用。该发明还涉及某些二取代单氢硼烷和芳基或烯烃硼酸酯。
