四元环 meaning in English
four-membered rings
tetra-atomic ring
Examples
- Four - member ring and six - member ring mechanisms have been studied , both of which have three reaction paths with the main path through two - step transition state
探讨了四元环和六元环机理，其中每种机理有三种途径，主要的途径是经过过渡态的两步反应途径。 - The study shows that though four - member ring transition state mechanism without solvent participation could explain the reduction of p - methylcyclohexanone reasonably , the calculated ratio of enantiomers could not match the experimental result
计算结果表明，无溶剂参与反应的四元环过渡态机理虽然能解释其还原历程，但计算所得的对映体组成与文献值相差很大。
