Budén, María E.,Heredia, Micaela D.,Puiatti, Marcelo,Rossi, Roberto A.
supporting information, p. 228 - 239 (2021/12/29)
A synthetic approach towards the 6H-benzo[c]chromene ring under visible light and transition-metal-free conditions has been developed. Benzochromenes are synthesized from the corresponding (2-halobenzyl) phenyl ethers or (2-halophenyl) benzyl ethers using
Ultrasound-promoted intramolecular direct arylation in a capillary flow microreactor
Zhang, Lei,Geng, Mei,Teng, Peng,Zhao, Dan,Lu, Xi,Li, Jian-Xin
experimental part, p. 250 - 256 (2012/04/23)
An intramolecular direct arylation of various aryl bromides was performed using ultrasonic irradiation and a continuous flow capillary microreactor. The present procedure provided a higher functional group tolerance, ligand-free, milder reaction condition

Palladium hydroxide on carbon (Pearlman's catalyst) effectively catalyzes direct arylation reactions of aryl iodides and bromides, providing excellent arylation-to-hydrodehalogenation ratios (>30:1) with broad scope for both intra- and intermolecular arylation processes. Studies aimed at determining the nature of the active catalyst indicate that an active homogeneous palladium species is produced under the reaction conditions.
