| Reactant | 2,4-Pentanediol | HCID 12262 | — |
| Reactant | (4-Nitro-benzyl)-phosphonic acid | HCID 5180708 | — |
| Product | 4,6-Dimethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinan-2-oxide | HCID 18928085 | — |
Reaction Steps
With 4-nitrobenzylphosphonic acid and 2,4-pentanediol, the same procedure as in Reference Example 11 was followed, to yield 4,6-dimethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinane-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless needles having a melting point of 152° to 153° C.
