Loss of CO2 from Monodeprotonated Phthalic Acid upon Photodissociation and Dissociative Electron Detachment

Large amounts of phthalic acid esters (PAEs) are leached from plastics dumped at municipal landfills. This leachate transports PAEs either adsorbed on particulate matter or in dissolved phase. Dissolved organic macromolecules, mainly humic-like substances, enhance the solubility of PAEs. In the biochemical environments of municipal landfills short chain PAEs can be degraded by base-catalyzed hydrolysis or by microorganisms which enzymatically split the side chains. However, there is no cleavage of the aromatic ring. Long chain PAEs like di-(2-ethylhexyl) phthalate are neither degraded abiotically nor by microorganisms. Hence, these PAEs can be leached and washed out of leaky landfills into the groundwater and thus continue to be a threat to the aquatic environment. Only a combined UV radiation/ozonation treatment is capable of fully destroying PAEs.

The N-trimethylsilyl compounds of the cyclic imides derived from cis-cyclohexan-1,2-dicarboxylic acid, cis-4-cyclohexen-1,2-dicarboxylic acid and phthalic acid were prepared. Reaction of the N-silylated cyclic imides 2 and 10 with 1,2,3,5-tetra-O-acetyl-β-ᴅ-ribofuranose in the presence of tin tetrachloride yielded the appropriate unusual ribonucleosides 4 and 12 whereas 14 led only to traces of the ribosylated derivative. The silylation and ribosylation sites in the aforementioned bicyclic imides were proved by 1H, 13C, and 29Si NMR spectroscopy and compared with data found for the monocyclic imides N-succinimide and N-maleinimide.
