Zn(NTf2)2Imidazolium-ILA facile, high yielding, and simple method for the synthesis of a library of dihydropyrimidinones (and -thiones) via the one-pot Biginelli reaction of aldehydes is reported. The method employs the Br酶nsted acidic IL [bmim(SO3H][OTf] or Zn(NTf2)2as catalyst along...

Acting as surrogates for aryldiazonium, 1‐aryltriazenes are readily unmasked with [BMIM(SO3H)][OTf] or Sc(OTf)3 and enter into cross‐coupling in widely available imidazolium‐ILs as solvent. The scope of this chemistry in the Suzuki, Heck, and Sonogashira reactions is explored. The ...
The CPBE experiments of ECR was performed in an all-glass gas-tight two-compartment electrochemical cell separated by a nafion (Alfa Aesar, Nafion® N-1178, 0.180 mm thick, ≥0.90 meq/g exchange capacity, Rf[OCF2CF(CF3)2]nOCF2CF2SO3H, 15 cm × 15 cm) membrane at room temperature...
