.alpha.-Trifluoromethyl-destabilized cations. A route to 1-(trifluoromethyl)tetralins by trifluoroacetolysis of 5-aryl-1,1,1-trifluoropentan-2-ols and derivatives
for hydrogenation of polycyclicaromatichydrocarbons (PAHs) containing 2–4 rings undermild reaction conditions. These compounds were partially hydrogenated with good to excellent selectivities just by optimizing the reaction conditions. The influence of the nature of substituents present in different positions of naphthalene on the selectivity of hydrogenation was also studied. Hydrogenation of products
Intramolecular Friedel-Crafts alkylation and chloroalkylation of 5-aryl-1,1,1-trifluoropentan-2-ones. A route to (trifluoromethyl)dihydronaphthalenes and (trifluoromethyl)tetrahydronaphthalenes
