Abstract
Starting from 2, 7‐diacetyl‐9, 10‐dihydrophenanthrene, 2, 7‐dichloromethyl‐9, 10‐dihydrophenanthrene was synthesized through a serie of a new compounds. By a modified Wurtz reaction the dichloromethyl compound led to hexahydro‐[23] (2,7) phenanthrenophane and decahydro‐[25] (2,7) phenanthrenophane. [23] (2,7) phenanthrenophane was obtained by dehydrogena tion of hexahydro‐[23] (2,7) phenanthrenophane with Pd/C. The structure of these new ring systems was confirmed by UV.‐, NMR.‐ and mass spectroscopy.Keywords
