Photochemical reaction of trialkylboranes in alcohols. Convenient synthesis of 2-alkyl-1,3,2-dioxaborolanes
Abstract
Irradiation of trialkylboranes (1) and propan-2-ol in n-hexane in air or nitrogen atmosphere produces the corresponding 2-alkyl-1,3,2-dioxaborolanes (2) in good yields; reactions in methanol and ethanol give similar results.
