halogenation reactions of 25 with chlorine gas or a solution of bromine in THF afforded protonated derivatives, [2-(Me2NH)CH2CH2N(Me)CH2}C6H4TeCl3]+(Cl)− (29a) and [2-(Me2NH)CH2CH2N(Me)CH2}C6H4TeBr3]+(Br) − (30a), respectively. The organomercury precursors; 2-Me2NCH2CH2N(Me)CH2}C6H4HgCl0.54/Br0.46 (31) and 2-Me2NCH2CH2N(Me)CH2}C6H4HgBr (32), were obtained by the reaction of 21 with HgCl2 and HgBr2 in
摘要我们报道了N,N',C螯合芳基二胺配体2- Me2NCH2CH2N(Me)CH2} C6H4Br(20)的有机碲(IV)/有机汞(II)衍生物的第一个实例的合成和表征。通过处理相应的格利雅试剂(21)/ [25]制备二卤化物[2- Me2NCH2CH2N(Me)CH2} C6H4Se] 2(24)和[2- Me2NCH2CH2N(Me)CH2} C6H4Te] 2(25)/有机锂试剂(22)在THF中分别含硒或碲。化合物[2- Me2NCH2CH2N(Me)CH2} C6H4] 2Se(26)和[2- Me2NCH2CH2N(Me)CH2} C6H4] Te(S2CN(CH2CH3)2(27)通过室温下以2:1的Se(dtc)2或1:1的Te(dtc)2(dtc =二乙基二硫代氨基甲酸酯)。相反,21与TeI2的反应提供了出乎意料的质子化衍生物[2-(Me2NH )CH2CH2N(Me)CH2}
