Preparation of the first fluorinated alkenyl isocyanide F2CCF–NC by flash vacuum pyrolysis of [Cr(CO)5(CN–CFCF2)]. Crystal and molecular structure of [Cr(CO)5(CN–CFCF2)] at 125 K
Abstract
Trifluorovinyl isocyanide, F2CCF–NC, is obtained by flash vacuum pyrolysis of [Cr(CO)5(CN–CFCF2)] at 240°C and identified by spectroscopic methods; the structure of the chromium complex [Cr(CO)5(CN–CFCF2)] has been elucidated by X-ray crystallography.
