HCID 189280695-Ethyl-5-methyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinan-2-oxide

Procedure

With 4-nitrobenzylphosphonic acid and 2-ethyl-2-methyl-1,3-propanediol, the same procedure as in Reference Example 11 was followed, to yield 5-ethyl-5-methyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinane-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless prisms having a melting point of 184° to 185° C.
