The synthesis, isolation, and characterization of several alkali metal aryl tellurolates of general formula (2,4,6-R3C6H2)TeM(sol) n (R Me, iPr, tBu; M Li, Na, K; sol = THF, n = 1.33, 1.5, 2.5, 3; sol = DME, n = 1; sol = TMEDA, n = 1; sol = 18-crown-6, n = 1) is reported. Reduction of (2,4,6-Me3C6H2)2Te2 and (2,4,6-iPr3C6H2)2Te 2 with 2 equiv of LiEt3BH in THF affords the corresponding lithium
几种通式(2,4,6-R 3 C 6 H 2)TeM(sol)n(RMe,i Pr,t Bu; MLi,报道了Na,K; sol = THF,n = 1.33,1.5,2.5,3; sol = DME,n = 1; sol = TMEDA,n = 1; sol = 18-crown-6,n = 1)。(2,4,6-Me 3 C 6 H 2)2 Te 2和(2,4,6- i Pr 3 C 6 H 2)2的还原在THF中具有2当量的LiEt 3 BH的Te 2提供相应的碲酸锂1和2。将Te直接插入(2,4,6- t Bu 3 C 6 H 2)Li(THF)3在THF中的CLi键中会生成3,而Te金属与(o -C 6 H 4的类似反应CH 2 NMe 2)Li提供螯合的碲铝酸盐4。Na / Hg汞齐对(2,4,6-Me 3 C 6 H 2)THF溶液的作用2 Te 2或(2,4,6- i Pr
