title: New insight into Ni(II)-catalyzed cyclization reactions of propargylic compounds with soft nucleophiles: novel indenes formation.
abstract: We have disclosed a very nice advance of nickel(II)-catalyzed carboannulation reactions. Highly substituted indene derivatives are readily prepared in moderate to excellent yields under very mild reaction conditions in air via a nickel(II)-catalyzed cyclization of propargylic compounds with soft nucleophiles.
