Application of the Arbuzov reaction to establish the structure of D-mannitol tricyclic triethyl triphosphite

The previously expressed theory that the tricyclic triethyl triphosphite of D-mannitol is 2-ethoxy-4, 5-bis-(2′-ethoxy-1′, 3′, 2′-dioxaphospholan-4′-yl)-l,3,2-dioxa-4-phospholane was corroborated on the basis of the differential-thermal analysis and31P NMR data.
