7-[(5,5-Dimethyl-2-oxido-1,3,2-dioxaphosphinan-2-yl)­oxy]-4-methyl-2H-chromen-2-one

The title compound, C15H17O6P, was obtained from a reaction of 4-methyl-7-hy­droxy­coumarin and 2-chloro-5,5-dimethyl-1,3,2-dioxaphosphinane 2-oxide. There are two mol­ecules in the asymmetric unit in which the benzopyran ring system is almost planar [r.m.s. deviation for each molecule = 0.003 Å]. I...
