Higher petroleum alkyltoluenes: Evaluation of thermodynamic maturity equilibrium between
isomers of higher petroleum alkyltoluenes with a normal alkyl chain have been discussed
Geometric isomers of 9-picolylideneazafluorenes-picolidene-1- and 4-azafluorenes, which we have isolated as pure Z and E
isomers. Using PMR spectroscopy we
