- TRANS-CYCLOHEXANE-l,2-DIOL (232 mg) and sodium
metaperiodate supported on silica gel (6.1 g, 10% loading) are stirred in dichloromethane (15 ml) (1) for 3 hours at 20 °C.
- The
solids are then filtered off and washed with dichloromethane (2 x 10 ml).
- Evaporation of the solvent from the combined filtrate and washings gives a
clear oil (185 mg, 80%) which is pure dial.
Notes to keep in mind:
1. The dichloromethane is distilled from phosphorus
pentoxide and stored over molecular sieves.
