The gas-phase kinetic and theoretical results are discussed in terms of a probable concerted, asynchronous, nonpolar mechanism, whereas the solution kinetics, which include extensive solvent effect studies, are discussed in terms of a polar mechanism which probably involves formation of a zwitterionic intermediate.
已在气相和溶液中获得了导致CO(2)和1,1-二氟烯烃的α,α-二氟β-内酯1的热分解速率,并报道了活化参数。还报道了对氟和非氟化β-内酯体系的从头算。气相动力学和理论结果是根据可能的一致,异步,非极性机理进行讨论的,而溶液动力学(包括大量的溶剂效应研究)是按照极性机理进行了讨论的,而极性机理可能涉及两性离子中间体的形成。 。
