The distributions of alkylated fluoren-9-ones and carbazoles, including their benzo- and dibenzo- and/or naphtho-annellated derivatives, have been investigated in rock extracts from a maturity sequence of Posidonia Shales from the Hils Syncline of northwest Germany. The fluoren-9-one and carbazole derivatives are quantitatively the most important compound types in the low polar heterocompound fraction...
The low-polarity NSO compound fraction of Posidonia Shale bitumens has previously been shown to contain fluoren-9-ones and benzofluoren-9-ones as the quantitatively most abundant compound class. The present study, based on detailed gas chromatography-mass spectrometry describes the distribution of naphthaldehydes, alkylnaphthylketones, benzaldehydes, alkylphenylketones, 1-indanones and 1-tetralones...
