Photoinduced Cyclizations of o-Diisocyanoarenes with Organic Diselenides and Thiols that Afford Chalcogenated Quinoxalines

This study describes the syntheses of 2,3-bis(selanyl)quinoxalines via the photoinduced cyclizations of o-diisocyanoarenes with diaryl or dialkyl diselenides, in addition to providing a detailed discussion of the corresponding mechanism and revealing that the developed procedure can also be applied to prepare 2-thiolated quinoxaline derivatives from o-diisocyanoarenes and thiols. The developed technique does not need the use of additives or metal catalysts and features the advantages of a high conversion, a broad substrate scope, and mild reaction conditions, thereby rendering it a valuable addition to the quinoxaline synthesis toolbox.

Iodinated (Perfluoro)alkyl Quinoxalines by Atom Transfer Radical Addition Using ortho-Diisocyanoarenes as Radical Acceptors

A simple method for the preparation of functionalized quinoxalines is reported. Starting from readily accessible ortho-diisocyanoarenes and (perfluoro)alkyl iodides, the quinoxaline core is constructed during (perfluoro)alkylation by atom transfer radical

A Preparative Method for o-Diisocyanoarenes

A general method for the preparation of o-diisocyanoarenes in moderate to good yields has been developed by the dehydration of o-di(formamido)arenes with trichloromethyl chloroformate at -78 deg C to 0 deg C.
