摘要

A remarkable catalytic effect of antimony (II1) chloride is disclosed in palladium (0)-catalyzed conjugate addition of aromatics to a&unsaturated ketones and aldehydes with sodium tetraphenylborate and arylboronic acids in acetic acid at 25" C. Several other metal chlorides such as Ac13, SnCl4, AsC13, TiC14, FeCl3, Mock, and CeCls are also effective in some cases, but SbCl3 is the salt of choice. Two key steps are proposed for this reaction: ...
