Novel vinylgallium intermediates occur in the β‐silylvinylation of aromatic hydrocarbons with trimethylsilylacetylene in the presence of GaCl 3 at− 78 C (see below). The interaction of silylacetylene and GaCl 3 initially generates a highly electrophilic cationic species, which is attacked by arenes at the β‐carbon atom. L Cl, Me.
