An efficient method for the dehydrogenative coupling of silanes with alcohols under photocatalysis was developed. The reaction proceeded in the presence of Ru(bpy)3Cl2 (0.5 mol%) under visible light irradiation in acetonitrile at room temperature. The developed methodology was also applicable for the synthesis of silanols using water as a coupling partner.

C-lignin biopolymers can be efficiently depolymerized into catechol derivatives with 85% yield and 91% selectivity at room temperature and ambient pressure in highly concentrated form (300 mg mL−1) over an organoborane catalyst.
