Abstract
Expression of concern for ‘Photo-triggered C-arylation of active-methylene compounds with diazonium salts via an electron donor–acceptor (EDA) complex’ by Shikha Pandey et al., Chem. Commun., 2024, 60, 1136–1139, https://doi.org/10.1039/D3CC05356C.
ChemComm is publishing this expression of concern to alert its readers that concerns have been raised regarding the identity of the products from the addition reaction.
The authors have been asked to carry out further experimental work to confirm the conclusions of their paper, and an expression of concern will continue to be associated with this article until a final outcome is reached.
