We report a diaryldiselenide catalyst for cross-dehydrogenative nucleophilic functionalization of hydrophosphoryl compounds. The proposed organocatalytic cycle closely resembles the mechanism of the Atherton–Todd reaction, with the catalyst serving as a recyclable analogue of the halogenating agent employed in the named reaction. Phosphorus and selenium NMR studies reveal the existence of a P–Se bond
A cobalt-catalyzed strategy for N-arylmethylation of phosphorylamides was herein achieved with the assistance of azodiisobutyronitrile as the radical initiator and di-tert-butyl peroxide as the oxidant. Both methylarenes and diaryl methanes were compatible under the oxidativeconditions, expressing broad substrate scope (51 examples) and high efficiency (up to 87% yield).
