Environmentally benign contemporary Friedel–Crafts acylation of 1-halo-2-methoxynaphthalenes and its related compounds under conventional and nonconventional conditions

This study highlights environmentally benign simple and practical methods for the selective acylation of 1-halo-2-methoxynaphthalenes, anisole, 2-methoxypyridine, and 2-methoxypyrimidine in the presence of cationic micelles (CTAB and CTAC) under conventional and nonconventional (ultrasound and micro...

Description
Summary:This study highlights environmentally benign simple and practical methods for the selective acylation of 1-halo-2-methoxynaphthalenes, anisole, 2-methoxypyridine, and 2-methoxypyrimidine in the presence of cationic micelles (CTAB and CTAC) under conventional and nonconventional (ultrasound and microwave) conditions for the first time. Environmentally benign simple and practical method has been developed in cationic micellar media for the selective acylations of 1-halo-2-methoxynaphthalenes, 2-methoxynaphthalene, anisole, 2-methoxypyridine, and 2-methoxypyrimidine. Developed protocols afforded good to excellent yields of products in the presence of a catalytic amount of cationic micelles (CTAB and CTAC) under conventional and nonconventional (ultrasonic and microwave) conditions.
