A bimetallic copper/palladium catalyst system is disclosed that enables the use of tosylates as carbon electrophiles in decarboxylative coupling reactions. A variety of aromatic carboxylate salts, regardless of their substitution pattern, have been coupled with these inexpensive and readily available electrophiles to give the corresponding biaryl compounds in good yields (see scheme).
公开了双金属铜/钯催化剂体系,其能够在脱羧偶联反应中使用甲苯磺酸盐作为碳亲电体。各种芳香族羧酸盐,无论其取代方式如何,均已与这些廉价且易于获得的亲电试剂偶联,以高收率得到相应的联芳基化合物(参见方案)。
