Geometrical Remote Steric Effects in 4,5-Disubstituted-9,10-dihydrophenanthrenes: Expansion of Prestrained C9–C10 Bond in Di(spiroacridan) Derivatives

By attaching bulky substituents at the bay region of di(spiroacridan)-substituted dihydrophenanthrene 1a, the prestrained C9–C10 bond in the dihydrophenanthrene (DHP) skeleton of 1c–1e is expanded from 1.634(2) to 1.649(3)–1.652(6) Å, which demonstrates the bond expansion through remote steric effec...
