GRAPHICAL ABSTRACT Abstract: The tert-butyl peroxide–initiated, oxidativecoupling of phenols can frequently promote reactions that otherwise perform poorly under alternative conditions. Despite this utility, peroxide coupling reactions employing conventional heat often require high-dilution conditions, multiple additions of oxidant, and long reflux times, while regularly affording only moderate product

Facile synthetic routes to a chiral chloro-substituted biphenyl-2,2′-diyl hydrogen phosphate and a chiral O,O-biphenyl-2,2′-diyl phosphoramidothioate are described. The performance of these compounds as catalysts for the hydrophosphonylation of imines and the Friedel–Crafts alkylation of indole was investigated. In the latter reaction, the chloro-substituted phosphoric acid derivative was found to
