[reaction: see text] Diaryl-, divinyl-, and dialkylindium proved to be stable in aqueous media and to undergo a palladium-catalyzed cross-coupling reaction with aryl halides in aqueous THF. Treatment of 3-iodophenol with diphenylindium compound, generated from indium trichloride and two equimolar amounts of a phenyl Grignard reagent, in aqueous media under palladium catalysis provided the corresponding
[反应:见正文]二芳基,二乙烯基和二烷基铟在水性介质中证明是稳定的,并与芳基卤化物在THF水溶液中进行钯催化的交叉偶联反应。在钯催化下,在水性介质中,用三氯化铟和两个等摩尔量的苯基格氏试剂生成的二苯基铟化合物处理3-碘苯酚,可得到相应的偶联产物,收率很高。二乙烯基铟和二乙基铟可在水存在下用于偶联反应。包括羟基和甲酰基在内的各种官能团均与该反应相容。
