CoCrPt films for longitudinal recording media were investigated as a function of substrate bias applied during the deposition. CoCrPt films were deposited on an underlayer stack consisting of glass/NiAl/CrMn with bias applied only during deposition of the CoCrPt layer. A strong dependence of the CoCrPt coercivity on the substrate bias was observed when a(More)
Highly functionalized 5-trifluoromethyl-2-isoxazoline derivatives featuring a triflyl (SO2CF3) group at the 4-position were successfully synthesized via diastereoselective trifluoromethylation and halogenation of isoxazole triflones using the Ruppert- Prakash reagent. The trifluoromethylation is quite general in terms of the substrates including 3,5-diaryl(More)
Regioselective conjugate 1,4-trifluoromethylation of α,β-unsaturated ketones by the use of shelf-stable electrophilic trifluoromethylating reagents, S-(trifluoromethyl)diphenylsulfonium salts and copper under mild conditions is described. A wide range of acyclic aryl-aryl-enones and aryl-alkyl-enones were converted into β-trifluoromethylated ketones in low(More)
