Synthesis and physico-chemical properties of ionic liquids—3-methyl-1-alkyloxycarbonylmethylpyridinium hexafluorophosphates
摘要:
Ionic liquids based on 1-alkyloxycarbonylmethyl-3-methylpyridinium and Cl- and PF6- anions have been synthesized. The conductivity of their solutions in acetonitrile and the thermal stability over 25-500 degrees C in air have been determined.

Norbormide [5-(α-hydroxy-α-2-pyridylbenzyl)-7-(α-2-pyridylbenzylidene)-5-norbornene-2,3-dicarboximide] (NRB), an existing but infrequently used rodenticide, is known to be uniquely toxic to rats but relatively harmless to other rodents and mammals. However, one major drawback of NRB as a viable rodenticide relates to an evolutionary aversion developed by the rat leading to sub-lethal dosing due to
Distannoxane catalysts effect acylation of alcohols by action of esters and acetic anhydride. In particular, use of enol esters provides an extremely useful method. Primary alcohols are acylated in preference to secondary ones as well as phenol. Both acid- and base-sensitive functional groups remain intact. Especially unique is the discrimination of thio function which is completely tolerant under
