Triafulvene (C 4 H 4 ), the simplest member of the fulvene family, is formed as the nascent product upon reaction of methylidyne radicals (CH) with allene (CH 2 CCH 2 ) and methylacetylene (CH 3 CCH). As shown by A. M. Mebel, R. I. Kaiser, and co‐workers in their Research Article on page 15488, the formation of triafulvene is favored due to the cycloaddition of the CH radical to unsaturated C 3 H 4 bonds followed immediately by the elimination of atomic hydrogen.
