Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Ethyl-2-methyl-1,3-propanediol | HCID 66169 | — |
| Reactant | (4-Nitro-benzyl)-phosphonic acid | HCID 5180708 | — |
| Product | 5-Ethyl-5-methyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinan-2-oxide | HCID 18928069 | — |
Reaction Steps
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.
