| The study of gas-phase ion/molecule reactions at atmospheric pressure opens a new field in the realm of physical organic chemistry. These preliminary studies shed light on the gap between condensed and conventional gas-phase studies and also which reactions are most appropriate for atmospheric study. The ion/molecule reaction to form the Meisenheimer complex of TNT and methyl nitrate under conventional high vacuum conditions has now also been observed at atmospheric pressure. In addition, the Eberlin transacetalization, occurring between tetramethylurea and 2-methyl-1,3-dioxolane, has been shown to also occur at atmospheric pressure. Additional reactions are performed using tetramethylthiourea which has shown to have different reactivity than its oxygen analogue, a difference worthy of further investigation. In addition, initial studies of the serine octamer at atmospheric pressure have shown the cluster fragments into the monomer and dimer upon thermal activation. Also, it has been demonstrated that threonine and cysteine may be substituted into the protonated serine octamer. Additional experiments may show whether chiral selectivity occurs for these reactions. |
