Methyl 3-pentenoate → Methyl 3-methoxyvalerate

Participants

Reaction Steps

10 g/hour of methyl 3-methoxyvalerate were pumped into an evaporator and passed from there, in gaseous form together with 3 l of nitrogen, at 300° C., over 5 g of an Al2O3 catalyst. The gaseous reaction products were condensed, weighed and analysed by gas chromatography. In the course of a reaction time of 6 hours, 49 g of reacted mixture consisting of 37% of methyl 3-pentenoate, 33% of methyl 2-trans-pentenoate, 5% of methyl 2-cis-pentenoate, 1% of methyl 4-pentenoate and 22% of unconverted methyl 3-methoxyvalerate were obtained. The ratio of 3-pentenoates to 2-pentenoates was accordingly 1:1.
