The Simmons–Smith reaction offers a direct route for conversion of an alkene into a cyclopropane with a zinc carbenoid as the active intermediate. Zinc carbenoids however have never delivered a...

A concept for pincer chemistry: internal aromaticity involving metal d-orbitals Stable cyclic rhodium complexes with obvious rhodium carbene character Dual stabilization of rigid CCC pincer architectures and intrinsic aromaticity Rhodium-containing aromatics with a single metal entity

A rhodium-catalyzed oxidative decarbonylative Heck-type coupling of aromatic aldehydes and terminal alkenes to afford 1,2-disubstituted alkenes with good regio- and E-selectivity is developed.
