Fearless Fluorine: the effect of gem-diflurination on acidity/basicity (pKa), lipophilicity (LogP), aqueous solubility (Sw), and metabolic stability (intrinsic clearance, CLint) of functionalized C3−C7-cycloalkanes is established and compared to those of non-fluorinated and acyclic counterparts. While the pKa values are varied similarly for the cyclic and acyclic series and can be explained by the
Fearless Fluorine:gem -diflurination 对官能化 C 3 -C 7 -环烷烃的酸度/碱度 (pK a )、亲油性 (Log P )、水溶性 ( S w ) 和代谢稳定性(固有清除率,CL int )的影响建立并与非氟化和无环对应物进行比较。虽然循环和非循环系列的 p K a值变化相似,并且可以通过氟原子的感应效应来解释,但 Log P和S w趋势更复杂。CL整数宝石二氟化后的值保持不变或略有改善。
