The Brønsted leaving group (β1g) plot for the alkaline hydrolysis of fluorene-9-carboxylate esters in the pH region corresponding to the existence of the ester anion shows a minimum flanked by a region of high negative β1g(-1·01), corresponding to an E1cb pathway and, for esters of pK1g > 9·5, a region of positive β1g(+0·11).
所述布朗斯台德离去基团(β 1克)情节在pH区域对应的酯阴离子示出了最小的侧翼由高负的区域存在芴-9-羧酸酯的碱性水解β 1克(-1·01)中,对应于一个ë 1 CB通路和,对于p的酯ķ 1克> 9·5,正的区域β 1克(+ 0·11)。
