The zip file contains txt files with absorbance vs. time data; exp files used for the k(obs) determination; pdf files with results of the k(obs) determination; xlsx fils with experimental details (concentrations, volumes, wavelengths, in German). Main folders refer to the solvents used for the kinetic measurements (that is, DMSO, MeCN, DCM, and THF). Subfolders and file names AB-xx and AEM-xxx refer to individual experiments and are identical to those in this Supporting Information. This Supplemental Material is part of an article published in the European Journal of Organic Chemistry (doi.org/10.1002/ejoc.202400373).
