Description acceptable. A reaction that increases this value is named for its hydrated imidazoline intermediate formed in basic methanol. The high dilution principle recommends synthesizing molecules with large values for this property at low input concentration to suppress concatemers (“con-CAT-uh-mers”). Carbyne cations like chloro·diazirine increase this value in a strategy popularized by Mark Levin (-5[1])for diversifying pharmacophores (“far-MACK-uh-fores”). Büchner’s carbene reaction increases this value (-5[1])for (15[1])arenes. Two of camphor’s (*) three values for this property increase after a Baeyer–Villiger oxidation. Step-changes to this (10[1])property are a common goal of skeletal editing. (10[1])The Beckmann rearrangement in nylon synthesis increases this value (10[1]-5[1])by one, (-5[2])forming caprolactam from cyclohexane. (10[1])For 10 points, name this geometric property that can exceed 30 atoms in macrocycles. (10[1])■END■ (10[6]0[1])
