Description

Description générale

Methyl 4-pentenoate is an unsaturated methyl ester that is prepared by the esterification of 1-pentenoic acid with methanol. It undergoes amidation with formamide via acetone-initiated photochemical reaction to form a 1:1 adduct. The metathesis of methyl 4-pentenoate with different Mo(VI)alkylidene complexes have been reported. It acts as a chain transfer agent during the polymerization of exo,exo-5,6-bis(methoxymethyl)-7-oxabicyclo[2.2.1]hept-2-ene using Ru^II(H₂0)₆(tos)₂ (tos =p-toluenesulfonate) as a catalyst.
