Getting out of the way: In fluorinated cyclododecane structures the CF2 group locates only at corner positions (see picture). This relaxes 1,4‐H,H transannular interactions as a result of C‐CF2‐C angle widening. Misplaced CF2 groups lead to significant ring distortion. It follows that strategic incorporation of CF2 groups has potential as a design feature to introduce order and polarity into organic
避开障碍:在氟化环十二烷结构中,CF 2基团仅位于拐角位置(参见图片)。由于C‐CF 2 ‐ C角变宽,这会放松1,4‐H,H跨环相互作用。CF 2基团放错位置会导致明显的环畸变。因此,CF 2基团的战略性掺入具有作为将有机碳结构中的有序和极性引入的设计特征的潜力。
