Diphenyl telluroketone, coordinated to pentacarbonyl tungsten, added to diethylamino-ethynes to produce 3,3-diphenyltellurono-2-propenoic diethylamides that remain coordinated to tungsten through the tellurium atom3. 

Diaryl-l,2,4,5-tetrazines, when treated with bulky amides such as lithium di-isopropylamide, undergo two competing reactions. In the first, tetrazine is reduced with concomitant formation of an imine from the amide. The imine is then attacked further by amide to give a pyridazine. For example, 3,6-diphenyl-l,2,4,5-tetrazine is converted with lithium diethylamide into 3,6-diphenylpyridazine in low yield. With lithium di-isopropylamide, 4-methyl-3,6-diphenylpyridazine is obtained in moderate yield [83JCS(P1)1601]. 

NaNH2 in HMPA reacts at 45-50°C with diphenyl imines. The anion is alkylated in medium yields. In this case, best results are obtained with the use of lithium diethylamide (ref. 37). Tosylhydrazones are converted into ethylenic compounds (Fig. 6) by treatment with NaNH2 in decaline (ref. 38).
