With Cleavage of One Te —C Bond

One Te-C bond in a diorgano tellurium can be cleaved by alkali metals, organic lithium compounds, sodium hydroxide, lithium aluminum hydride, sodium borohydride, Grignard reagents, tributyltin hydride, sulfuric acid, sodium sulfide, sulfuryl chloride, hydrogen bromide, bromine, or iodine. The Te-C bond can also be broken thermally or through photostimulation. [Pg.472]

Recently a novel approach to the synthesis of telluranthrene has been suggested (91 KGS 1203) this employs a reaction between poly (o-phenylene)ditelluride and butyllithium. The assumed mechanism of formation of telluranthrene 92 (M = Te) is founded on the known ability of the Te—C (87AG1221) and Te—Te (63CB247) bonds to cleave under the action of organolithium compounds. One of the products of this cleavage, o-dilithiobenzene, reacts with poly(o-phenylene)ditelluride affording tellurantrene in approximately 30% yield. [Pg.95]
