摘要:非配位溶剂允许在环戊二烯存在下由二卤代和三卤代苯前体通过卤素金属交换诱导形成苯炔(芳烃),从而生成1,4-二氢-1,4-甲基-萘.对混合卤化物前体和非酸性diels-Alder二烯陷阱的研究表明,醚和烃类溶剂会影响卤化物的离去基团,从而逆转3-卤代苯炔的区域选择性.

摘要:A process to synthesize substituted phenols such as those of the general formula RR'R''Ar(OH) wherein R, R', and R'' are each independently hydrogen or any group which does not interfere in the process for synthesizing the substituted phenol including, but not limited to, halo, alkyl, alkoxy, carboxylic ester, amine, amide; and Ar is any variety of aryl or hetroaryl by means of oxidation of substituted arylboronic esters is described. In particular, a metal-catalyzed C-H activation/borylation reaction is described, which when followed by direct oxidation in a single or separate reaction vessel affords phenols without the need for any intermediate manipulations. More particularly, a process wherein Ir-catalyzed borylation of arenes using pinacolborane (HBPin) followed by oxidation of the intermediate arylboronic ester by OXONE is described.
