4-methyl-1-methyltelluro

The following compounds are the most popular donors for organic metals (see Scheme 8.9) TTF, tetraselenafulvalene (TSeF), tetrathiatetracene (TTT), tetraselenatetracene (TSeT), tetra-methyl tetraselenafulvalene (TMeTSeF), bis(thiadimethylene) tetrathiafulvalene (BTDM-TTF), bis(ethylenedithia) tetrathiafulvalene (BEDT TTF or ET), tetrakis(methyltelluro) tetrathiafulvalene (TTeCj-TTF), tetramethylbis(ethylenedithia) tetrathiafulvalene (TMET), 2,2 -(2,6-naphthalenediy-lydene) bis(l,3-dithiole) (NBDT). All the abbreviations are those used in the current literature. 

Reaction of methanetellurol with lithium aluminum hydride in diethyl ether caused liberation of hydrogen and formation of lithium tetrakis[methyltelluro]aluminate. This compound was not isolated but reacted with silyl or germyl halides to give silyl or germyl methyl tellurium derivatives4. 

Lithium tetrakis[methyltelluro]aluminate, prepared from methanetellurol and lithium aluminum hydride, reacted with silyl, germyl, and stannyl halides at low temperatures to produce, for instance, methyl silyl tellurium derivatives1. 

Methyl iodide methylated the tellurium atom in trialkylphosphane tellurides at room temperature with benzene as the reaction medium. The trialkyl(methyltelluro)phosphoni-um iodides precipitated as colorless to yellow solids2. 

The methylation of (/(-tellurido)bis[7t5-cyclopentadienyl(tricarbonyl)]chromium by methyl trifluoromethanesulfonate in diethyl ether at 20° produced a methyltelluro-bridged complex that was isolated as the hexafluorophosphatc2. The red-brown solid forms needles that are stable in air for a short time only. 

Methyl 2-chlorophenyl tellurium was quaternized by excess methyl iodide in refluxing acetone. 1,2-Bis[methyltelluro]benzene formed the ditelluronium compound under these conditions. When the ort/io-substituent in methyl 2-X-phenyl tellurium is a methoxy, methylthio, or methylseleno group that is also capable of quaternization, excess methyl iodide in refluxing acetone quaternizes only the methyltelluro group9.

The reaction of elemental tellurium with cesium 3-cowwo-3-cobaltabis[decahydro-l,2-dicarba-c/ojo-dodecaborate] in acetic anhydride/sulfuric acid and the methylation of the resulting product with dimethyl sulfate produced 8,8 -methyltelluro-3-commo-3-cobaltabis[l,2-dicarba-closo-dodecaborane] in low yield. ... 

The air-sensitive dialkylstibano methyl tellurium compounds can be distilled under reduced pressure without disproportionation into tetraalkyldistibane and dimethyl ditellurium. Even at elevated temperature, disproportionation was not observed. However, diethylstibano methyl tellurium tends to decompose to triethylstibane and bis[methyltelluro] ethylstibane. ...
