t-BuONa-Mediated Transition-Metal-Free Autoxidation of Diarylmethanes to Ketones

Abstract

Autoxidative sp³ C–H transformation of diarylmethanes has been demonstrated using O₂-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.

Key words

Ketones - benzyl derivatives - autoxidation - metal-free - oxygenation

• 16 Typical Procedure for t-BuONa-Mediated Autoxidation of Diarylmethanes to Ketones: To a predried 5-mL round-bottom flask diarylmethane 1a (0.4 mmol, 67 mg, 1 equiv), anhyd DMSO (0.4 mol/L), and t-BuONa (0.8 mmol, 77 mg, 2 equiv) were subsequently added as soon as possible. The reaction system was sealed by a rubber septum with a needle connected to an O₂ balloon, and then stirred at 50 °C for 1 h. During this period, the reaction system suffered complex color changes. The usual workup afforded the desired ketone 2a as a white solid (yield: 92%, 67 mg); mp 48–49 °C. ¹H NMR (400 MHz, CDCl₃): δ = 7.81 (d, J = 7.7 Hz, 4 H), 7.59 (t, J = 7.3 Hz, 2 H), 7.48 (t, J = 7.5 Hz, 4 H). ¹³C NMR (101 MHz, CDCl₃): δ = 196.8, 137.6 (2 × C), 132.4 (2 × C), 130.1 (4 × C), 128.3 (4 × C). EI–MS: m/z = 182.0 [M]⁺.
