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 the Supporting Information files "OpenData_SI_2-pyNHO_kinetics.docx/pdf/rtf". This Supplemental Material is part of an article published in the European Journal of Organic Chemistry (doi.org/10.1002/ejoc.202400373). Keywords: kinetics, reactivity, nucleophiles, electrophiles, time-resolved spectroscopy Methods for data collection: time-dependent photometric measurements ______________________________ File list: 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 (MS Excel) with experimental details (concentrations, volumes, wavelengths, in German) File formats: *.txt (raw data), *.exp (evaluated data), *.xlsx (protocol data), *.pdf (evaluated data, Supporting Information), *.docx (Supporting Information), *.rtf (Supporting Information) ______________________________ Remarks: We thank the Deutsche Forschungsgemeinschaft (NMR: DFG project 452669591) under Germany's Excellence Strategy EXC2033, project number 390677874-RESOLV.
