A highly enantioselective Friedel-Crafts reaction of pyrrole derivatives with N-acyl imines catalyzed by chiral phosphoric acids was developed. The reactions produced the pyrrole derivatives in high yields and enantioselectivity.
The invention relates to new compounds containing alkyl-alkoxy-cyano- borate anions, their preparation and their use, in particular as part of electrolyte formulations for electrochemical or optoelectronic devices.

Provided is a method for manufacturing a tricyclodecane mono-methanol monocarboxylic acid derivative that can be used as a raw material for high heat-resistant alicyclic polyesters and the like.
The provided method for manufacturing a tricyclodecane mono-methanol monocarboxylic acid derivative is characterized in that a tricyclodecane mono-methanol monocarboxylic acid derivative represented by the following formula (III) is obtained by reacting the dicyclopentadiene represented by the following formula (I) with a formic acid compound in the presence of a catalytic system containing a ruthenium compound, a cobalt compound, and a halide salt, to give a tricyclodecene monocarboxylic acid derivative represented by the formula (II), and then hydroformylating the tricyclodecene monocarboxylic acid derivative.
(in the formulae (II) and (III), R represents a hydrogen, an alkyl group having 1 to 5 carbon atoms, a vinyl group, or a benzyl group.)
