Sodium hydrogen telluride, sodium 0,0-diethyl phosphorotellurolate, alkali 2-thienyl tellurolates and bis(triphenylstannyl) telluride °/KF reduce a-haloketones to the corresponding ketones.

In a rare example of the use of iodonium salts for heteroatom-heteroatom bond formation, diaryliodonium halides were employed with sodium 0,0-diethyl phosphoroselenolate for a one-pot synthesis of diaryl diselenides (Scheme 9) [27]. These transformations probably occur via arylation of the phosphoroselenolate salt with the diaryliodonium ions, hydrolysis of the resulting aryl phosphoroselenolates with sodium hydroxide, and air oxidation of the arene-selenide ions thus produced. 

Sodium 0,0-diethyl tellurolophosphate deoxygenates terminal oxiranes quickly, cyclohexene oxide slowly, and trans-internal oxiranes very slowly2- 3. The yields of olefins are higher than 70%. 

Triphenylphosphine selenide, potassium selenocyanate, 3-methyl-2-selenoxobenzothiazole sodium 0,0-diethyl phosphorotelluronate," 0,0-dialkyIphosphoroselenoic acid salts" and benzenese-lenocarboxamide, have all been reported as reagents capable of one-step deoxygenation of epoxides. 

The thermal instability of the telluriranes is also utilized in the transformation of epoxides to alkenes <77CC658, 80JOC2347). When epoxides are treated with sodium 0,0-diethyl phos-... 

Another example of the formation of tellurirane using a nonheterocyclic tellurium compound has been shown in the reaction of sodium 0,0-diethyl phosphorotelluroate (45) with a-haloketones (62). As shown in Scheme 11, the starting a-haloketones (62) are converted into the corresponding dehalogenated parent ketones (63) via epitelluride intermediate (64) together with the formation of elemental tellurium. 

Thermally labile telluriranes can also be generated from oxiranes by treatment with sodium 0,0-diethyl phosphorotelluroate, and this reaction was especially applied to the selective deoxygenation of terminal epoxides (see Section 1.07.6.2). 

Sodium telluride and sodium 0,0-diethyl phosphorotellurolate, prepared respectively by the Te/NaBFt4DMF method and by the reaction of elemental tellurium with NaH and 0,0-diethyl phosphate in ethanol, react with arenediazonium fluoroborates, giving good yields of diaryl tellurides. ... 

Demeton-S (56) can also be prepared directly by the reaction of sodium 0,0-diethyl phosphorothioate with ethyl-2-chioroethyl sulfide or by the reaction of diethyl phosphorochloridate with sodium 2-ethylthioethyl mercaptide (Schrader, 1950a 1950b). 

Phorate can be prepared by the reaction of diethyl phosphorodithioic acid, ethyl mercaptan and formaldehyde (Hook and Moss, 1948), or by the reaction of sodium 0,0-diethyl phosphorodithioate with ethylthiomethyl chloride (Lorenz and Schrader, 1952).

Sodium dithionite in water or aqueous dimethylformamide is an economic, efficient system for the dehalogenation of a-halo-ketones. Other reagents that have been described recently for dehalogenation include iron-graphite (prepared by reduction of ferric chloride with potassium-graphite), sodium 0,0-diethyl phosphorotelluroate, and sodium borohydride in the presence of a catalytic amount of bis(2-thienyl) ditelluride. ... 

Thiols, silyl thioethers, and thiosaccharins" may be benzylated with benzyl bromide under basic conditions. Thus u-cysteine is 5-benzylated under basic conditions (eq 2). Benzylation of selenols is likewise possible. A synthesis of benzylic sulfones is possible using Benzenesulfonyl Chloride and Sodium 0,0-Diethyl Phosphorotelluroate with benzyl bromide. ...
