Folder and file names AEM-xxx refer to individual experiments and are identical to those in the Supporting Information files "OpenData_SI_cyclopropanesPAC2023.docx/pdf/rtf". The isolated product 2-(2-((4-methoxyphenyl)thio)ethyl)malononitrile was NMR spectroscopically characterized (AEM-080-01_xxxx.fid). This Supplementary Material is part of an article published in Pure and Applied Chemistry (doi.org/10.1515/pac-2023-0209). Keywords: kinetics, reactivity, nucleophiles, electrophiles, time-resolved conductometry, NMR spectroscopy Methods for data collection: time-dependent conductometry measurements (kinetics), NMR spectroscopy (product characterization) ______________________________ File list: The zip file contains *.txt files with voltage vs. time data (raw data) and *.fid files with unprocessed NMR data of 2-(2-((4-methoxyphenyl)thio)ethyl)malono-nitrile (raw data) File formats: *.txt (raw data), *.fid (raw data), *.pdf (Supporting Information), *.docx (Supporting Information), *.rtf (Supporting Information) ______________________________ Remarks: This research was funded in whole, or in part, by the Austrian Science Fund (FWF), project no. J-4592 (Erwin Schroedinger fellowship to A.E., Grant-DOI: 10.55776/J4592).
