Synthesis, spectroscopic and structural studies of O-methyl and O-isopropyl monothiocarbonate (monoxanthate) derivatives of dimethyl-and diphenyltellurium(IV). Crystal structures of Me2Te[SCO2(i-Pr)]2, Ph2Te[SCO2(i-Pr)]2, Me2TeCl[SCO2Me], and Me2TeBr[SCO2(i-Pr)]
Tetraorganotin compounds react with telluriumtetrachloride or telluriumtetrabromide with formation of the corresponding organotellurium trihalides and diorganotellurium dihalides. 125Te NMR spectra of the reaction mixtures are used to determine the reaction products.
四有机锡化合物与四氯化碲或四溴化碲反应,形成相应的有机卤化三碲和二卤化二有机碲。反应混合物的125 Te NMR光谱用于确定反应产物。
Nuclear quadrupole resonances of α-(CH3)2 TeX2 (X=Cl, Br, I) and (CH3)2 TeI4
observed for α-(CH 3 ) 2 TeX 2 (X=Cl, Br, I) and (CH 3 ) 2 TeI 4 at various temperatures. The two 81 Br NQR lines were observed above 110 K in α-(CH 3 ) 2 TeBr 2 . The characteristic temperature dependence of the 127 I NQR line in α-(CH 3 ) 2 TeI. can be explained by the 3c—4e bond of the linear ITeI group. The positive temperatures dependence of the lowest 127 I NQR line in (CH 3 ) 2 TeI 4 is discussed
