Abstract
A number of indenes have been prepared in good yields by treatment of o-bromobenzyl zinc bromide with various terminal and internal alkynes in the presence of a nickel catalyst. The nickel-catalyzed carboannulation reaction was successfully extended to the synthesis of indanes using acrylates and styrenes instead of an alkyne.
