Water → 2,15-Hexadecanedione

Participants

Reaction Steps

0.37 g (1 mmol) of dimethyl 2,13-bisacetyl-1,14-tetradecanedioate were dissolved in 20 ml of DMSO and refluxed with 0.06 g (0.1 mmol) of sodium chloride and 0.04 g (2 mmol) of water for 3 h at 155 to 160° C. For work-up, the DMSO is firstly distilled off under reduced pressure, and the residue is distilled using a bulb tube. This gives 0.21 g of hexadecane-1,15-dione. Accordingly, the yield of 1,15-hexadecanedione is 82%, based on 1,9-decadiene.
