Procedure

The compound is prepared in accordance with Method B described above, using 1 equivalent of dimesitylfluoroborane and 1 equivalent of diphenylisopropoxyborane. The crude product is obtained by concentrating the reaction mixture under a high vacuum and treating the solid residue, under argon, with hexane. Filtration, concentration of the filtrate and recrystallization of the residue from acetonitrile give 3.0 g (61% of theory) of the pale yellow title product, which is sensitive to air. Physical data are given in Tabelle 1.
