Constituents of cigarette smoke. Part XI. The isolation and synthesis of acenaphthylenes and macrocyclic polyolefins

Abstract

Acenaphthylene, the monomethylacenaphthylenes, and some dimethylacenaphthylenes have been identified in cigarette smoke condensate. Some of the acenaphthylenes were synthesised, as was also a perhydro-macrocycle (X). The possible formation of cromatic compounds from macrocyclic polyolefins is discussed, and the isolation of such a macrocycle from cigarette smoke is described. The mass spectra of some acenaphthylenes are described.
