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, C23H17SeCl0.5ZnCl2, 265-268C, 57.5; 2,6-diphenyl-4-(n-methoxyphenyl)selenium pyrylium chlorozincate, C24H19SeO3Cl0.5ZnCl2, 262-264C, 60.5; 2,4,6-tri-(n-methoxyphenyl)selenium pyrylium chlorozincate C24H21SeO3Cl0.5ZnCl2, 238-241C, 71 are described. ^ EFFECT: avoiding of gaseous hydrogen selenide formation ^ 1 cl, 3 ex |
