Participants
| Role | Name | HCID | Charge |
|---|
| Reactant | Triethyl phosphite | HCID 31215 | — |
| Reactant | 4-Bromobenzyl bromide | HCID 68527 | — |
| Product | Diethyl (4-Bromobenzyl)phosphonate | HCID 11077666 | 89.5% |
Reaction Steps
203.6 g (815 mmol) of 4-bromobenzyl bromide and 215 ml (1.2 mol) of triethyl phosphite are mixed and heated at 130° C. for 1 h with gas discharge. The product is then subjected to fractional distillation (2×10−2 mbar, 120° C.), giving 224 g (89%) of the product as a colourless liquid.
