- W808778897 abstract "디시클로헥실 텔루르염은 에탄올 수용액에서 NaTeH와 디시클로헥실 브롬화물의 반응에 의해 높은 수율로 얻어진다. 일반식 <TEX>${(cyclo-C_6H_11)}_2Te(R)X$</TEX> (where R = <TEX>$CH_3$</TEX>, X = I (1); R = <TEX>$C_2H_5$</TEX>, X = Br(2); R = <TEX>$C_2H_5$</TEX>, X = I (3); R = <TEX>C_3H_5$</TEX>, X = Br (4)) 인 유기텔루로늄의 새로운 시리즈는 그에 상응하는 알킬 할로겐화물과 <TEX>${(cyclo-C_6H_11)}_2Te$</TEX>의 반응에 의해 만들어진다. <TEX>$NaBPh_4$</TEX>와 1의 반응은 78% 수율로 화합물 5를 제공하였다. 벤질 브롬화물과 <TEX>${(cyclo-C_6H_11)}_2Te$</TEX>, 4-bromophenacyl bromide의 반응에서는 뜻밖에 각각dibenzylcyclohexyltelluronium 브롬화물과 and bis(4-bromophenacyl)cyclohexyltelluronium bromide을 얻었다. 높은 수율의 tetraphenylborate 유도체는 <TEX>$NaBPh_4$</TEX>과 6의 반응으로 얻었다. <TEX>$CDCl_3$</TEX>용매에서 <TEX>$^1H$</TEX> NMR분석을 통해 화합물 1 이 알킬 할로겐화물의 제거 반응을 일으킴을 확인할 수 있었다. 새로운 화합물은 전도성, IR, <TEX>$^1H$</TEX>와<TEX>$^{13}C$</TEX> NMR, 열분석를 통해 규명되었다. Dicyclohexyl telluride was obtained in a high yield by the reaction of cyclohexyl bromide with NaTeH(prepared in situ) in an aqueous ethanolic solution. A series of new organotelluronium salts of the general formula <TEX>${(cyclo-C_6H_11)}_2Te(R)X$</TEX> (where R = <TEX>$CH_3$</TEX>, X = I (1); R = <TEX>$C_2H_5$</TEX>, X = Br(2); R = <TEX>$C_2H_5$</TEX>, X = I (3); R = <TEX>C_3H_5$</TEX>, X = Br (4)) were prepared by the reaction of <TEX>${(cyclo-C_6H_11)}_2Te$</TEX> with the corresponding alkyl halide. Reaction of 1 with NaBPh4 gave compound 5 ( i.e. R = CH3, X = BPh4 ‒) in 78% yield. Reaction of <TEX>${(cyclo-C_6H_11)}_2Te$</TEX> with benzyl bromide and 4-bromophenacyl bromide gave unexpectedly dibenzylcyclohexyltelluronium bromide (6) and bis(4-bromophenacyl)cyclohexyltelluronium bromide (7), respectively. Reaction of 6 with NaBPh4 gave the corresponding tetraphenylborate derivative (8) in high yield. <TEX>$^1H$</TEX> NMR studies revealed that in <TEX>$CDCl_3$</TEX>solution compound 1 eliminated alkyl halide. Conductivity, IR, <TEX>$^1H;and;^{13}C$</TEX> NMR and thermal data for the new compounds are presented and discussed." @default.
