Synthesis
Commonly used tellurium based reagents are hydrogen telluride, NaHTe, sodium telluride, and PhTeLi. Because Te is insoluble and polymeric, it is often not a useful precursor to organotellurium compounds, but it is attacked by hydride reducing agents:
- Te + 2LiBHEt3 → Li2Te + H2S + 2 BEt
and organolithium compounds:
- Te + RLi → RTeLi
One departure from S and Se chemistry, is the availability of the tetrachloride TeCl4. Tellurium tetrachloride reacts with alkenes and alkynes to the chloro tellurium trichloride addition product:
- RCH=CH2 + TeCl4 → RCH(Cl)-CH2TeCl3
These organotellurium derivatives are susceptible to further reactions.

Famous quotes containing the word synthesis:
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
“In order to begin an analysis, there must already be a synthesis present in the mind.”
—Johan Huizinga (1872–1945)
“If in the opinion of the Tsars authors were to be the servants of the state, in the opinion of the radical critics writers were to be the servants of the masses. The two lines of thought were bound to meet and join forces when at last, in our times, a new kind of regime the synthesis of a Hegelian triad, combined the idea of the masses with the idea of the state.”
—Vladimir Nabokov (1899–1977)
