Data for Catalytic Stereoselective Intermolecular Fluoroacylation of Unactivated Alkynes via C–F Bond Reconstruction

Data collection method:

Full experimental details for the preparation of each compound can be found in the Supplementary Information of the associated paper.

Technical details and requirements:

1H NMR, 13C NMR and 19F NMR spectra were obtained on a Bruker Avance, a Bruker Avance 400 (400 MHz 1H, 101 MHz 13C, 376 MHz 19F) or a Bruker Avance 500 (500 MHz 1H, 126 MHz 13C, 471 MHz 19F) spectrometer at room temperature in the solvent stated. NMR yields were obtained using 0.33 equiv. of trifluorotoluene as an internal standard. Infrared spectra were recorded on a Shimadzu IRAffinity-1 Fourier Transform ATIR spectrometer as thin films using a Pike MIRacle ATR accessory. High-resolution mass spectrometric (HRMS) data were obtained on a Waters MALDI-TOF mx in Cardiff University.

Additional information:

NMR data are presented in the following format: chemical shift (multiplicity [s = singlet, br = broad, d = doublet, t = triplet, q = quartet, p = pentet dd = doublet of doublets, dt = doublet of triplets, dq = doublet of quartets, ddd = doublet of doublet of doublets, m = multiplet], coupling constant [in Hz], number of equivalent nuclei by integration). Spin-spin coupling constants J are given in Hz and refer to apparent multiplicities rather than true coupling constants. Data are reported as: chemical shift, multiplicity and integration. Infrared spectra were recorded with absorbance peaks quoted (νmax/cm-1).
