Aerobic Photooxidative Synthesis of Secondary Aldimines from Benzylamines by Using Methylene Blue

Abstract

We have developed a concise oxidative coupling of primary benzylamines to yield secondary aldimines catalyzed by methylene blue by using molecular oxygen as the oxidant in the presence of visible-light irradiation from fluorescent lamps.

Key words

aerobic - methylene blue - photooxidation - singlet oxygen - primary amine - imine

• 23 General Procedure A solution of 4-tert-butylbenzylamine (1a, 0.3 mmol), K₂CO₃ (3.7 equiv), and MB (1.0 mol%) in dry MeCN (5 mL) in a Pyrex test tube, purged with an O₂ balloon, was stirred and irradiated externally with four 22 W fluorescent lamps for 10 h. Products were purified by filtration through a pad of silica gel (3 mm thick) with Et₂O, and the filtrate was concentrated.
