Abstract: Efficient synthesis of ionic liquids based on stereoisomerically pure natural and synthetic higher (5Z,9Z)-alkadienoic acids and choline hydroxide was developed. The key unsaturated carboxylic acids were prepared using the stereoselective cross-cyclomagnesiation reaction of aliphatic and oxygen-containing 1,2-dienes with EtMgBr in the presence of Mg metal and Cp₂TiCl₂ catalyst.

Keywords: cross-cyclomagnesiation, Grignard reagents, allenes, titanocene dichloride, (5Z, 9Z)-alkadienoic acids, choline, ionic liquids.
