Someone who says “A” should be prepared to also say “B”: In contrast to cyclohexane model‐based A values, biphenyl model‐derived B values are powerful tools to quantify steric repulsion in and conformational behavior of ortho‐substituted aromatic compounds.
应该说“ A”的人也要说“ B”:与基于
环己烷模型的A值相比,
联苯模型得出的B值是量化邻位取代的芳族化合物的空间斥力和构象行为的有力工具。
