Mi. Ruzaeva et al., Synthesis and chemical specifics of bicyclophosphites and bicyclophosphoramidites derived from anthracene-1,4,9,10-tetraol, RUSS J G CH, 70(9), 2000, pp. 1363-1367
Anthracene-1,4,9,10-tetraol was reacted with amides, amidoesters, and other
derivatives of phosphorous acid to obtain first representatives of bicyclo
phosphites in whose molecules the anthracene system is fused with 1,3,2-dio
xaphosphorinane. The structure of the products was examined by NMR and X-ra
y diffraction.
