Site-Selective C–H Functionalization on Coumarins Directed by Manganese: Mechanistic Insights from Time-Resolved Spectroscopy and Catalytic Development

3DED/microED datasets collected using a Thermo Fisher Scientific Glacios microscope equipped with a Ceta-D Camera for samples 1b (TJB-2-050), 2c (TJB-2-072) and 2d (TJB-3-068) associated with the publication "Site-Selective C–H Functionalization on Coumarins Directed by Manganese: Mechanistic Insights from Time-Resolved Spectroscopy and Catalytic Development" Data collection details: 200kV, nanoprobe, gun lens 8, spot size 11, 30 µm C2 aperture. Illuminated area was 1.05 µm. Under these conditions flux is 0.07 e-/Å^2/s. Camera length calibrated from Al powder was 958.5 mm. Data acquired using EPU-D with following settings: 2x binning, 1.33°/s, 0.75s exposure, rolling shutter, noise reduction mode enabled. MRC format images can be processed with DIALS using the FormatMRC dxtbx format (distributed with DIALS from version 3.5 onwards), use goniometer.axes=1,0,0.
