This article reviews synthetic transformations involving cleavage of a carbon–carbon bond of
a four-membered ring, with a particular focus on the examples reported during the period …

The transition-metal-catalyzed intramolecular hydroarylation of alkenes has been
recognized as a straightforward approach for the construction of 3, 3-disubstituted 2, 3 …

A tandem reaction that involves an unprecedented Rh-catalyzed intramolecular annulation
of benzocyclobutenols with alkynes and subsequent ZnCl2-promoted dehydration was …

Although transition-metal-catalyzed C–C bond activation has been investigated extensively,
C–C bond cleavage manipulated by hydrogen transfer has been unexplored. In this work …

A Pd-catalyzed skeletal rearrangement of 3-allyloxybenzocyclobutenols was achieved,
which involved successive proximal C–C bond cleavage, C–O bond cleavage and C–H …

Catalytic construction of oxindoles bearing all-carbon-quaternary centers attracts wide
attention from the synthetic chemistry community. Herein, we report a palladium-catalyzed …

A mechanism study of iridium-catalyzed intermolecular cyclization of ring-fused
benzocyclobutenols with alkynes is described using density functional theory (DFT) …
