Boron trifluoride etherate; highly efficient catalyst for synthesis of tert-butylamides via modified Ritter reaction in solvent free condition
Highly efficient method for the preparation of N-tert-butyl amides by reaction of nitriles with tertbutylacetateis described using boron trifluoride etherate in solvent free condition. Selective amidation ofbenzonitrile in the presence of acetonitrile was also achieved.
متن کاملEnhanced molecular order in polythiophene films electropolymerized in a mixed electrolyte of anionic surfactants and boron trifluoride diethyl etherate.
We synthesized polythiophene (PTh) films on stainless steel electrodes using chronoamperometry in boron trifluoride diethyl etherate (BFEE) electrolyte with anionic surfactants. The presence of the anionic surfactants in BFEE reduced the oxidation potential of thiophene and increased the oxidation current during electropolymerization. The measured in-plane electrical conductivity of PTh films s...
متن کاملPechmann reaction promoted by boron trifluoride dihydrate.
The Pechmann reaction of substituted phenols 1a-e with methyl acetoacetate (2) can be activated by boron trifluoride dihydrate (3) to give the corresponding 4-methyl- coumarin derivatives 4a-e in excellent yield (98-99 %).
متن کاملSynthesis of C-Glycosides from S-Glycosyl Phosphorothioates
Treatment of O-benzyl protected S-glucosyl phosphorothioates with 1,3,5-trimethoxybenzene in the presence of iodine or boron trifluoride etherate led to appropriate aryl C-Dglucosides. The reaction of O-benzyl and O-acetyl-protected phosphorothioates of monosaccharides with allyltrimethylsilane, using boron trifluoride etherate as activator, gave mainly or exclusively, the corresponding 3-(α-Dg...
متن کاملSynthesis of oxabicyclo[3.3.1]nonenes and substituted tetrahydropyrans via (3,5)-oxonium-ene reaction.
An efficient methodology for the synthesis of oxabicyclo[3.3.1]nonenes and substituted tetrahydropyrans has been developed in moderate yields from the reaction of geraniol with aldehydes and epoxides promoted by boron trifluoride etherate.
