First representatives of quinolino-1,3,2-dioxaphosphorinanes
摘要:
Cyclophosphorylation of 7-(1,1,1,3,3,3-hexafluorohydroxyisopropyl)-8-hydroxyquinoline with trivalent phosphorus reagents affords the first representatives of quinolino-1 ,3,2-dioxaphosphorinanes. The crystal structure of 4,4-bis(trifluoromethyl)-2-diethylamino-2-thio(quinolino-7,8)-1,3,2-dioxaphosphor(V)inane has been studied. A substantial effect of substituents at the P atom on the conformation of the phosphor(V)inane fragment of the molecule has been established.
