Crystal structures of the polymer precursors 3-(2,5-dimeth-oxy-3,4,6-tri-methyl-phen-yl)propyl methacrylate and 3-(2,4,5-trimethyl-3,6-dioxo-cyclo-hexa-1,4-dien-yl)propyl methacrylate.
The closely related title compounds, 3-(2,5-dimeth-oxy-3,4,6-tri-methyl-phen-yl)propyl methacrylate, C18H26O4 (I), and 3-(2,4,5-trimethyl-3,6-dioxo-cyclo-hexa-1,4-dien-yl)propyl methacrylate, C16H20O4 (II), are monomers suitable for the preparation of redox polymers. They consist of a propyl-methacrylate group and three methyl substituents on di-meth-oxy-benzene and quinone cores, respectively. Both crystal structures feature weak C-H⋯O hydrogen bonds and C-H⋯π(ring) contacts between methyl groups and the six-membered rings.
