Versuchsvorschrift

A solution of 28 g of 8-benzylidene-1,4-dioxa-spiro[4.5]decane and 1 g of 5% palladium on carbon in 250 mL of ethanol was allowed to stir overnight under 1 atm of hydrogen. The catalyst was filtered off and the solution concentrated to give 28 g of 8-benzyl-1,4-dioxa-spiro[4.5]decane as an oil.

Aufarbeitung
