Homma, Yuki published the artcileRuthenium-catalyzed regio- and site-selective ortho C-H borylation of phenol derivatives, Recommanded Product: 3-Chloro-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol, the publication is Chemical Communications (Cambridge, United Kingdom) (2020), 56(73), 10710-10713, database is CAplus and MEDLINE.
Efficient synthesis of o-borylphenols, e.g. I, is achieved through the Ru-catalyzed regio- and site-selective sp2 C-H borylation of aryl diphenylphosphinites followed by removal of the phosphorus directing group. A successful application to aryl phosphites enables practical one-pot borylation of phenols, demonstrating high synthetic utility of this protocol.
