Selective Enzymatic Oxidation of Silanes to Silanols [PDF]

, 2020
Compared to the biological world's rich chemistry for functionalizing carbon, enzymatic transformations of the heavier homologue silicon are rare. We report that a wild‐type cytochrome P450 monooxygenase (P450_(BM3) from Bacillus megaterium, CYP102A1 ...

Silylboronate-Mediated Defluorosilylation of Aryl Fluorides with or without Ni-Catalyst

Frontiers in Chemistry, 2021
The defluorosilylation of aryl fluorides to access aryl silanes was achieved under transition-metal-free conditions via an inert C–F bond activation. The defluorosilylation, mediated by silylboronates and KOtBu, proceeded smoothly at room temperature to ...
