Acenaphthene,
acenaphthylene, and 1-acenaphthenol were obtained from SigmaAldrich (St. Louis, MO) or Wako Pure Chemical (Osaka).
1,2-Epoxy
Acenaphthene (1,2-acenaphthenyl oxide) was prepared by the stepwise reaction of
acenaphthylene with two molar equivalents of 3-chloroperbenzoic acid (previously washed with base and dried to remove 3-chlorobenzoic acid) in a CH
2Cl
2-phosphate buffered system:
