In(III)-Mediated Chemoselective Dehydrogenative Interaction of ClMe2SiH with Carboxylic Acids: Direct Chemo- and Regioselective Friedel−Crafts Acylation of Aromatic Ethers
摘要:
Chemoselective dehydrogenative interaction of ClMe2SiH with a carboxylic acid group in the presence of InX3 is reported. C-13 NMR investigation revealed the formation of PhCOOSi(Cl)Me-2 as the major transient intermediate. Chemo- and regioselective Friedel-Crafts acylation of aromatic ethers directly from carboxylic acids was established.
