Aromaticity has been used as a criterion to explain the gas chromatographic (GC) retention of cata-condensed polycyclic aromatic sulfur heterocycles (PASHs) C12H8S, C16H10S, C20H12S; and peri-condensed PASHs C18H10S, in a GC column with 50% phenyl/50

An efficient synthesis of potentially carcinogenic dibenzo[a,l]tetracene 1 and dibenzo[a,j]tetracene 2 has been developed and the synthetic standards were used to establish their environmental presence. The synthesis involves Diels–Alder reaction o
