Response to “Evidence for ‘holey graphyne’ is questionable”

We thank Valentin O. Rodionov et al. for their interest in our holey graphyne (HGY) paper and for giving comments on the organic reaction mechanism and related modes of reaction, which greatly help researchers gain further insights into these types of novel carbon materials with unusual sp bonds. In response, we have carefully considered the reaction mechanism and conducted all related modes of reaction. Below, please find our explanations and clarifications. Evidence for "holey graphyne" is questionableValentin O. RodionovMatterMarch 06, 2024In BriefRichard F. Heck, Ei-ichi Negishi, and Akira Suzuki were awarded the 2010 Nobel Prize in Chemistry for their pioneering work on palladium-catalyzed cross-couplings. This class of reactions has vastly expanded the possibilities for chemists to create bonds involving low-reactivity sp2 carbon sites. A recent article1 by Liu et al. would appear to transcend the achievement of Heck, Negishi, and Suzuki. The authors claim to have synthesized an allotrope of carbon ("holey graphyne" or "HGY") incorporating highly strained cyclooctadiyne rings. Full-Text PDF
