Page/Page column 5-7, (2013/02/27)
A process for preparing esters and organic halides, which comprises reacting - a salt having a melting point of less than 100°C (at 1 bar) and of the formula ???????? (K+)n X (COO-)n, in which K+ is an organic cation, X (COO-)n is an organic anion having an n-valent organic group X which is substituted by n carboxylate groups COO-, and n is 1, 2 or 3, - with an organic halogen compound (Hal)mY, in which Hal is a halogen atom, Y is an m-valent organic group, and m is 1, 2 or 3, to give an ester and a halide K+ Hal-.

, (2008/06/13)
The invention relates to a process for preparing haloalkanes by reaction of alcohol with hydrogen halide, wherein the reaction of the alcohol with the hydrogen halide occurs in the presence of an ionic liquid at a temperature which is above 100° C. for at least part of the time and, at least at the time of the commencement of the reaction, the water content is not more than 25 mol % based on the amount of liquid, where the ionic liquid is not octyltrimethylammonium chloride.

By metathesis between lithium salts of 7,7,8,8-tetracyano-p-quinodimethane and 1-methyl-3-alkylimidazolium bromides, simple radical salts were prepared whose specific electrical conductivity values are c. 10-7 - 10-3, Ω-1 m-1, according to the donor structure.Combining these salts with neutral 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) gave complex salts with an electrical conductivity higher by 7-3 orders of magnitude which increases monotonically with increasing volume of the alkyl group.The compounds are stable in anhydrous conditions also in presence of oxygen, and if irradiated by daylight.The rate constant of hydrolysis of these salts is proportional to the water content in solution and inversely proportional to the content of neutral TCNQ in the simple radical salt.The hydrolysis is predominantly activated by light absorbed by the decomposition products.
