ethyl (2E,4E)-hexa-2,4-dienoate

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

Procedure: A mixture of 10 mmol of ethyl acrylate, 100 mmol of n-propyl alcohol, 1 mmol of N-hydroxyphthalimide, 0.01 mmol of cobalt(II) acetate, 0.1 mmol of acetylacetonatocobalt(III), and 54 mmol of acetonitrile was stirred at 50° C. in an oxygen atmosphere (1 atm) for 8 hours. A reaction mixture was concentrated, and the concentrate was subjected to column chromatography on a silica gel to yield ethyl 2,4-dihydroxyhexanoate, γ-ethyl-α-hydroxy-γ-butyrolactone, and ethyl sorbate in yields of 14%, 40%, and 2%, respectively. The conversion rate from ethyl acrylate was 72%. A reaction mixture was concentrated

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

Procedure: For example, when n-propyl alcohol is allowed to react with ethyl acrylate, ethyl 2,4-dihydroxyhexanoate corresponding to the formula (4) and 4-ethyl-2-hydroxy-γ-butyrolactone corresponding to the formula (6) are formed under some conditions, in addition to the target ethyl sorbate.

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

Procedure: For example, when n-propyl alcohol is allowed to react with ethyl acrylate, ethyl 2,4-dihydroxyhexanoate corresponding to Formula (4) and 4-ethyl-2-hydroxy-65-butyrolactone corresponding to Formula (6) are formed in addition to the target ethyl sorbate under some conditions.
