Spectral data for the synthesis of ()-alkenylboronic acid pinacol esters hydroboration of alkynes.

This data article is related to a research paper entitled "Solvent- and metal-free hydroboration of alkynes under microwave irradiation" (Gioia et al. TETL-D-19-01698) [1]. Herein we present the spectral data acquired from the synthesis of ()-alkenyl boronic acid pinacol esters. The data include the general information and the synthetic procedure affording the target derivatives, which were fully characterized by Nuclear Magnetic Resonance (H and C NMR) and, for the most part, by Electrospray Ionization High Resolution Mass (ESI-MS). Proton and carbon NMR spectra and ESI-MS spectra were provided which will be useful for further organic chemists if they are interested in the synthesis of these building blocks.
