bicyclo[2.2.1]heptane-2,2-dimethanol synthesis

Yield: 92.9%

Reaction Conditions:

with 5%-palladium/activated carbon;hydrogen in ethanol for 6 h;

Steps:

1 Preparation of 2,2-norbornanedimethanol
Preparation Example 1
Preparation of 2,2-norbornanedimethanol
138.18 g of 5-norbornene-2,2-dimethanol (commercially available from Tokyo Kasei Industry Co., Ltd.) was dissolved in 481.63 g of ethanol, and 6.92 g of 5% Pd-C was added, then a hydrogen balloon was attached and the mixture was stirred for 6 hours.
The Pd-C was filtered off, then the reaction solution was concentrated and dried to thereby obtain 129.83 g of 2,2-norbornanedimethanol (purity by gas chromatography: 99.1%, yield: 92.9%).
