The new 6H-dibenzo[c,e][1,2]oxaphosphinine 6-sulfide (1) was synthesized and characterized by 1H-, 13C-, 31P-NMR, IR spectroscopy as well as X-ray diffraction and HR-MS. The reactivity of (1) was investigated with a series of test reactions, including Michael-type additions and the Atherton-Todd-reaction and finally compared to that of the parent 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide.

This article discusses the behavior of seven organophosphorus compounds under Atherton-Todd conditions. Therefore, the reactivity and selectivity of different (phen)oxaphosphinines, dioxaphosphinines, dioxaphosphinanes, and diphenylphosphine oxide with three nucleophiles were systematically studied. The results prove the versatility of the Atherton-Todd reaction to a broad range of organophosphorus compounds with different phosphorus environments and reactive Pi-H bonds. The nucleophiles studied in this article were chosen as model substrates for amines and alcohols. Because organophosphorus molecules are important and versatile compounds, for a broad field of applications, novel synthetic approaches are of interest to both academia and industry. As an example, the single-step synthesis of the bridged 1,3-phenylene bis(diphenylphosphinate) with potential flame-retardant properties was added to this study. In addition, the reaction is utilized for the synthesis of a novel organophosphorus anhydride.
