Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:50501-07-0) here.
Binuclear platinum(II) diphosphite complexes as practical and efficient photocatalysts for oxidant-free and acceptorless dehydrogenation of alcs. and N-heterocycles in high yields even under substrate-limiting conditions was described. The reaction could be used for constructing quinazolin-4(3H)-ones from anthranilamide and alcs. This protocol offered the unique reactivity of binuclear platinum(II) diphosphite complexes, wide substrate scope, mild reaction conditions, scalability, utility and versatility of these photocatalysts with practical relevance. Regeneration of the photocatalyst by means of reductive elimination of dihydrogen from the in-situ formed platinum(III)-hydride species represented an alternative paradigm to the current approach in photoredox catalysis.
