Unprecedented noradamantane-type compounds [(R2,3Ge)4Te5] (R2 = CH2CH2COOH, R3 = CH(CH2COOH)2), containing a GeâGe bond, yield from reactions of R2,3GeCl3 with Na2Te or Li2Te in THF, while reactions with R1GeCl3 (R1 = CMe2CH2COMe) afford a double-decker-type cage [(R3Ge)4Te6]; by reaction with hydrazine, the latter reacts to the hydrazone functionalized, monomeric anion [(R4Ge)Te2]â (R4 = CMe2CH2CNNH2Me).
R2,3GeCl3与Na2Te或Li2Te在THF中反应生成了含有一个GeâGe键的前所未有的去金刚烷型化合物[(R2,3Ge)4Te5](R2 = CH2CH2COOH,R3 = CH(CH2COOH)2),而与R1GeCl3(R1 = CMe2CH2COMe)反应生成了双层型笼状化合物[(R3Ge)4Te6];与肼反应,后者会生成腙官能化的单体阴离子[(R4Ge)Te2]â(R4 = CMe2CH2CNNH2Me)。
