hexadecane-2,15-dione

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 38 g of hexadeca-5,11-diene-2,15-dione (0.152 mole) were dissolved in 200 ml of ethyl acetate and hydrogenated at 50° C. under standard conditions using 1.9 g of 10% strength Pd/C. Recrystallization from petroleum ether gave 25.8 g of a 97% strength hexadecane-2,15-dione of melting point 80° C. The yield was thus 66% of theory. Recrystallization from petroleum ether

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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. For work-up, the DMSO is firstly distilled off under reduced pressure the residue is distilled
