Preparation and Molecular Structures of 9,10-Dihydrophenanthrenes: Substituent Effects on the Long Bond Length
9,10-Dihydrophenanthrene derivatives 1−3 with electron-donating and/or -accepting groups at their 9,10-positions were prepared, and their precise molecular structures were determined by X-ray analyses at 203 K. The long C9−C10 bond [1.646(4) Å] in the hexaarylethane-type compound 1 with four electro...
