Autoxidative sp 3 C-H transformation of diarylmethanes has been demonstrated using O 2 -mediation by t-BuONa. This protocol enables an alternative route for the access to diaryl ketones from benzyl derivatives in good to excellent yields under mild reaction conditions, without transition metal catalysts or additional chemical oxidants.

An efficient and neat procedure for N‐acylation of anilines has been developed using 5‐(un)substituted Meldrum's acids as acyl surrogates under neutral conditions in excellent yields. This protocol features a solvent‐free and catalyst‐free acylation process, and enables facile access to a vast array of structurally versatile sec‐ and tert‐anilides.
