1,9-Decadiene is synthesised using 2-(oct-7-en-1-yl)oxirane as a raw material by chemical reaction. The specific synthesis steps are as follows:
General procedure: To a solution of Ni(acac)2 (25.7 mg, 0.1 mmol) in dry THF (3 mL) were successively added ethyl 3-phenylglycidate (192 mg, 1 mmol) and diethylzinc (2.4 mmol, 1.0 M hexane solution) via syringe under argon atmosphere. The mixture was stirred at ambient temperature for 48 h. The mixture was diluted with 30 mL of CH2Cl2 and washed with sat. NH4Cl aq. and then brine. The organic layer was dried over MgSO4 and concentrated in vacuo and the residual oil was subjected to column chromatography over silica gel (hexane/EtOAc = 4/1 v/v) to give 1,9-Decadiene (164 mg, 93%).
