Abstract

The first section of this study investigates the effect of low temperatures on [2+2] photocycloaddition reactions of a furan derivative, furyl acrylic acid, which can be derived from biomass, and its effect on various photoactive monomers. The experiments demonstrated that the furan derivative could dimerize in extreme temperatures (-196 oC) using liquid nitrogen with up to 82% conversion. The second chapter is dedicated to developing a more environmentally friendly reaction procedure for a different furan derivative, maleic anhydride, with simple olefins (specifically cyclohexene and 1-hexene). Traditionally, these reactions were performed with medium-pressure mercury lamps, conventional photochemical reaction vessels, and flow reactors, which all involve specialized equipment and are often expensive. This study successfully utilized more eco-friendly methods with repurposed plastic as the reaction vessel and ECO-UVA lights as the radiation source. Some low-temperature experiments with maleic anhydride and simple olefins were also done to limit polymer byproducts.
