PHOSPHINE-CONTAINING CALIXARENE LIGANDS, METHOD OF THEIR PRODUCTION AND USE Russian patent published in 2018 - IPC C07C47/02 C07C47/198 C07F9/50 B01J23/46 

FIELD: chemistry.

SUBSTANCE: invention relates to the production and use for the catalytic hydroformylation of olefins of phosphine-containing ligands of the general formula (1): ,

where R is selected from COOH, CONHC(CH₂OH)₃ or the solubilizing groups containing from 4 to 12 of the hydroxyl groups. These ligands are obtained by modifying bromine-substituted calixarene via the Arbuzov reaction with subsequent propargylation of the produced phosphinoxide-containing calixarene to produce the corresponding propargyl-containing calixarenes that are modified using tris (benzoyloxymethyl) methylamide 2-azidoethoxy acid to obtain the corresponding triazolopyridine calixarene, followed by recovery with phenylsilane, followed by hydrolysis. A new efficient method of producing new ligands with improved solubility in alcohols and a molecule size of more than 2 nm is proposed.

EFFECT: more efficient process of obtaining aldehydes and acetals in the catalytic hydroformylation reactions, the ability to separate the catalytic complex from the reaction products with the possibility of reuse.
