M. Kuroboshi et al., SYNTHESIS OF TRIFLUOROMETHYLAMINO-SUBSTITUTED PYRIDINES AND PYRIMIDINES BY OXIDATIVE DESULFURIZATION-FLUORINATION, Tetrahedron letters, 36(4), 1995, pp. 563-566
Oxidative desulfurization-fluorination of methyl N-pyridy-(or N-pyrimi
dyl)-N-alkydithiocarbamates gave the corresponding trifluoromethylamin
o-substituted pyridines (or pyrimidines), which underwent cross-coupli
ng reaction to give a new type of liquid crystalline compounds having
trifluoromethylamino group.
