In connection with another investigation, 2 a series of compounds has been made, which have a substituent in an angular position of partially or completely hydrogenated derivatives of 1, 2-cyclopentenonaphthalene or 1, 2-cyclopentenophenanthrene. The methods used were developments of those described earlier. 8~ 4~ 6, 6~ 7~ 8~ g The naphthalene derivatives were made through a series of reactions in which 2- ...
