Regio- and Stereoselective Dimerization of Arylalkynes Mediated by a Transient Zinc Radical
Vinyl radicals are crucial intermediates in synthetic chemistry that readily undergo a range of well-established transformations, such as hydrogen atom transfer and cyclization. Herein, we report a distinct reaction mode in which vinyl radicals, generated from the attack of a transient zinc radical on an alkyne, are...
