Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Methylbenzaldehyde | HCID 7725 | — |
| Reactant | Potassium Cyanide | HCID 9032 | — |
| Product | 4,4'-Dimethylbenzoin | HCID 224848 | — |
Reaction Steps
250 g (2.08 mol) of p-methylbenzaldehyde were condensed with the aid of 30 g (0.46 mol) of KCN to give 4,4′-dimethylbenzoin according to a standard method (Organikum 18th edition (1990) 457). The crude product was used without further purification (yield, crude: found: C, 80.0%, H, 6.4%. calculated: 79.97%, H, 6.71%). The IR spectrum of 4,4′-dimethylbenzoin is shown in FIG. 8.
