Abstract

The development of catalytic systems that facilitate simple yet valuable molecular transformations in a sustainable manner is of fundamental importance in the field of synthetic organic chemistry. Herein, we report the expedient application of a zwitterionic acridinium amidate, a recently developed direct hydrogen-atom-transfer catalyst, in catalytic acceptorless dehydrogenation (CAD). The combined use of the acridinium amidate with a cobaloxime complex and a protic additive as a catalyst system enables the CAD of hydrocarbons to proceed with high efficiency under mild reaction conditions.

Key word

acceptorless dehydrogenation - photocatalysis - zwitterions - hybrid catalysis - dehydrogenation - aromatization

  • 24 Acceptorless Dehydrogenation of 1,2,3,4-Tetrahydronaphthalene; Typical Procedure A flame-dried Schlenk tube equipped with a stirrer bar was charged with acridinium amidate 1 (1.6 mg, 0.003 mmol, 3 mol %), Co complex 2a (2.1 mg, 0.005 mmol, 5 mol %), and 2,4,6-collidinium tosylate (14.7 mg, 0.05 mmol). The tube was sealed with a rubber septum, evacuated, and backfilled with Ar five times, then DCE (500 μL) and 1,2,3,4-tetrahydronaphthalene (13.2 mg, 0.1 mmol, 1.0 equiv) were successively introduced into the Schlenk tube. The rubber septum was replaced with a glass stopper under a steady flow of Ar, and the tube was quickly evacuated and backfilled with Ar five times. The mixture was then stirred for 48 h under irradiation by two Kessil H150 Blue lamps, with fan cooling to maintain the temperature below 40 °C. The mixture was concentrated, and the yield of naphthalene was determined by GC-FID with 1,3,5-trimethoxybenzene as an internal standard [yield: 0.080 mmol (80%)].
