METHOD FOR PREPARATION OF 2,4,6-TRIARYLSELENIUM PYRYLIUM CHLOROZINCATES Russian patent published in 2009 - IPC C07D345/00

Abstract RU 2367658 C2

FIELD: chemistry.

SUBSTANCE: method for preparation of 2,4,6-triarylselenium pyrylium chlorozincates includes the interreaction of 1,3,5-aryl-substituted 1,5-diketones with hydrogen selenide obtained by dissolution of zinc selenide in the hydrogen chloride solution in diethyl ether. The reaction medium is obtained by reaction of phosphorus pentachloride with water in diethyl ether medium. The 2,4,6-triphenylselenium pyrylium chlorozincate, C₂₃H₁₇SeCl·0.5ZnCl₂, 265-268°C, 57.5; 2,6-diphenyl-4-(n-methoxyphenyl)selenium pyrylium chlorozincate, C₂₄H₁₉SeO₃Cl·0.5ZnCl₂, 262-264°C, 60.5; 2,4,6-tri-(n-methoxyphenyl)selenium pyrylium chlorozincate C₂₄H₂₁SeO₃Cl·0.5ZnCl₂, 238-241°C, 71 are described.

EFFECT: avoiding of gaseous hydrogen selenide formation
