General In(0)-catalyzed allylations of ketones proceeded smoothly in water under mild conditions, and water proved to be essential for these reactions. Both the substrate scope and the functional group tolerance were excellent. The In metal catalyst could be easily recovered and reused without loss of catalytic activity.
