Abstract

The reactions of 9-methyl-4-methylidene-3,5-dioxabicyclo[5.4.0]undecane with maleic anhydride and acrylonitrile were studied by NMR spectroscopy and were found to give 1:1 molecular complexes with equilibrium constants of 0.24±0.06 and 0.14±0.04 l mol−1, respectively. Analysis of the calculated (AM1) heats of formation ΔH, differences in the dipole moments Δμ, frequencies and intensities of stretching vibrations of the donor and acceptors, and charge distribution showed formation of π-π, mixed π-π-H, and H complexes with partial charge transfer. These complexes can be used in copolymerization of the above monomers.
