Method for directly preparing alkyl borate compound from alkyl halide
-
Paragraph 0166-0168, (2021/04/14)
The invention relates to a method for directly preparing an alkyl borate compound from an alkyl halide, which comprises the following steps: in a protective atmosphere, mixing a titanium metal catalyst, an alkali compound, a borate compound and an alkyl halide or sulfonate compound, reacting at 35-100 DEG C for 8-24 hours, so that the alkyl halide or sulfonate compound is directly converted into the alkyl boronic acid pinacol ester compound. The method is simple to operate, low in cost, good in functional group tolerance and wide in substrate application range.

We report operationally simple and neutral conditions for borylation of alkyl bromides and iodides to alkyl boronic esters under transition metal- and light-free conditions. A series of substrates with a wide range of functional groups were effectively transformed into the borylation products in moderate to good yields. Mechanistic studies, including radical clock experiments and DFT calculations, gave detailed insight into the radical borylation process.

The synthesis, characterization, and catalytic activity of low-spin {CoNO}8 pincer complexes of the type [Co(PCP)(NO)(H)] are described. These compounds are obtained either by reacting [Co(PCP)(κ2-BH4)] with NO and Et3N or, alternatively, by reacting [Co(
