Chromatography-mass spectrometry studies of transarylation and disproportionation reactions of diaryl telluroxides

Electrospray ionization chromatography-mass spectrometry was used to study transarylation and disproportionation reactions of di(4-methoxyphenyl) and di(4-dimethylaminophenyl) telluroxides in refluxing toluene. The reaction mixture compositions were estab

Debrominations of vic-Dibromides with Diorganotellurides. 1. Stereoselectivity, Relative Rates, and Mechanistic Implications

Debrominations of vic-dibromides with diaryl tellurides 1-4 and di-n-hexyl telluride (9) are described. A mechanistic explanation of the debromination is offered which accounts for several key experimental observations: (1) the reaction is highly stereoselective with erythro-dibromides giving trans-olefins and threo-dibromides giving cis-olefins, (2) the reaction is accelerated by more electron-rich diorganotellurides, (3) the reaction is accelerated in a more polar solvent, (4) the reaction is accelerated by the addition of carbocation-stabilizing substituents to the carbons bearing the bromo substituents, and (5) erythro-dibromides are much more reactive than threo-dibromides. It is proposed that bromonium ion formation from the vic-dibromide is slow and rate-determining. Bromonium ion formation is followed by rapid scavenging of "Br-" by the diorganotelluride. The bromonium ion formation provides stereoselectivity and eclipsing interactions lower the reactivity of threo-dibromides. No intermediate species were observed by 1H NMR.

Mild reduction of tellurium(IV) and selenium(IV) compounds by sodium ascorbate

Sodium ascorbate was found to mildly reduce organyltellurium trihalides to diorganyl ditellurides, organylselenium trihalides to diorganyl diselenides, diorganyltellurium dihalides and oxides to diorganyl tellurides and diorganylselenium dihalides and oxides to diorganyl selenides.

SYNTHESIS AND STRUCTURE OF AROMATIC AND HETEROCYCLIC COMPOUNDS OF TELLURIUM. XVIII. ABNORMAL THERMAL DISSOCIATION OF 2-DIORGANOTELLURIODIMEDONIDES

When 2-diorganotelluroniodimedonides are boiled in o-xylene cleavage of the ylide bond occurs, and the corresponding tellurides and the trimer of the carbanionic fragment, which is a derivative of the tetrahydrofuro-1,3-dioxepin system, are formed.
