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-[2 3](2, 7) phenanthrenophane and decahydro-[2 5](2, 7) phenanthrenophane.[2 3](2, 7) phenanthrenophane was obtained by dehydrogena tion of hexahydro-[2 3](2, 7) ...
