Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Benzoin | HCID 8400 | — |
| Reactant | 3,4-dihydro-2-methoxy-2H-pyran | HCID 91538 | — |
| Solvent | Benzene | HCID 241 | — |
| Product | HCID 131710645 | HCID 131710645 | 87.4% |
Reaction Steps
85 parts of benzoin are reacted with 68.4 parts (50% molar excess) of 2-methoxy-2,3-dihydro-4H-pyran in 120 parts by volume of benzene, analogously to Example 1. The resulting benzoin 2-methoxy-tetrahydropyranyl ether, obtained in a yield of 87.4% of theory, boils at 195° to 200° C/0.3 mm Hg and has the following structure: ##STR7## NMR spectrum (in CDCl3): δ = 1.0 -2.4 (multiplet, 6 protons)
