Abstract
A practical and straightforward protocol to access site-selective C-3 phosphorylated benzofulvenes by means of cross-dehydrogenative coupling of two nucleophilic moieties, employing silver as a promoter, is described here. Remarkably, this protocol provides a broad, structurally diverse phosphorylated benzofulvene. Initial mechanistic studies shed light on its radical coupling nature, and late-stage transformations offer highly diversified benzofulvenes core.

Abstract
A highly regioselective sequential 1,3-acyloxy migration/pentannulation/1,5-hydride migration reaction is disclosed which provides an efficient access to (E)-2-vinyl-3-oxo-1-methyleneindenes under neutral and mild reaction conditions. The migrated hydrogen atom was derived from an unactivated alkyl group, and the long-range 1,5-H shift was confirmed through related deuterium experiments.
