Diorganotellurium(IV) bis(fluorocarboxylates)[R2Te(OCOR')2] [R = Me, Ph,p-MeOC6H4 and p-EtOC6H4; R' = CF3, C2F5, C3F7] have been prepared by the interaction of R2Te(OMe)2 with fluorocarboxylic acids (R'COOH). Identical products were obtained by the metathetical reaction of R2TeCl2 with silver salts of the fluorocarboxylic acids in 1:2 molar ratios. However, when the reaction proceeded in a 1:1 molar ratio, the product
二有机碲(IV)双(氟代羧酸盐)[R 2 Te(OCOR')2 ] [R = Me,Ph,p -MeOC 6 H 4和p- EtOC 6 H 4 ; 通过R 2 Te(OMe)2与氟代羧酸(R'COOH)的相互作用制备了R'= CF 3,C 2 F 5,C 3 F 7 ] 。通过R 2 TeCl 2的易位反应获得相同的产物与氟羧酸的银盐的摩尔比为1:2。然而,当反应以1:1摩尔比进行时,产物为R 2 TeCl(OCOR')。然而,R 2 TeO与CF 3 COOH的反应产生了[(R 2 TeOCOCF 3)2 O] 2 ·H 2 O}和[(R 2 TeOCOCF 3)2 O]种类。产品在溶液中为非导电单体。根据理化和光谱(IR,质量,1 H,13 C,19 F和125 Te NMR)研究。
