Abstract

Expression of Concern for ‘Immobilized tetrakis(triphenylphosphine)palladium(0) for Suzuki–Miyaura coupling reactions under flow conditions’ by G. Valerie Ramaotsoa et al., React. Chem. Eng., 2019, 4, 372–382, https://doi.org/10.1039/C8RE00235E.


The Royal Society of Chemistry is publishing this expression of concern in order to alert readers that the authors have informed Reaction Chemistry & Engineering that the data in Table 5 is not reliable.

The authors are currently repeating the NMR experiments in order to confirm the reliability and accuracy of the data.

An expression of concern will continue to be associated with the article until we receive conclusive evidence regarding the reliability of the reported data.
