Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1,4-Butanediol | HCID 8064 | — |
| Reactant | (4-Nitro-benzyl)-phosphonic acid | HCID 5180708 | — |
| Product | 2-(4-Nitrobenzyl)-1,3,2-dioxaphosphepan-2-oxide | HCID 18928078 | — |
Reaction Steps
With 4-nitrobenzylphosphonic acid and 1,4-butanediol, the same procedure as in Reference Example 11 was followed, to yield 2-(4-nitrobenzyl)-1,3,2-dioxaphosphepane-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless needles having a melting point of 136° to 137° C.
