Triarylindium reagents

The addition of several trialkyl or triarylindium reagents to the acetates of MBH adducts proceeds readily under the catalysis of copper and palladium derivatives. The reactions of trialkylindiums are catalyzed efficiently by Cul whereas additions of triarylindiums produce better results with Pd(PPh3)4. The reactions with 3-acetoxy-2-methylenealkanoates provide ( )-alkenes 213,... 

In 2003 the first carbonylative coupling of indium reagents was reported both by Lee [90] and Sarandeses [91]. Asymmetrical ketones were produced by the carbonylative coupling of triaUtyl- and triarylindiums with aryl halides in the presence of a palladium catalyst under one bar of CO in THF at 66 °C (Scheme 4.50).
