Dimethylphosphano methyl

Das Phosphinsaure-amid I laBt sich nach Metallierung mit Butyl-lithium mit Chlor-dimethyl-phosphan zum au-Berst luftempfindlichen Dimethyl-phosphinsaure-(dimethylphosphano-methyl-umid)-methylimid (64°/0) umset-zcn"2 ... [Pg.295]

With the sterically demanding /TU-buty I diphosphane, the tellurium-phosphorus compound was quantitatively formed and disproportionation to ditellurium and diphosphane was not observed. After distillation of di-isopropylphosphano 4-methylphenyl tellurium, some tctraisopropyldiphosphane was observed. The diphosphane was observed spectroscopically after storage of the pure yellow-orange oil for a few days at 20r 4. Dimethylphosphano methyl tellurium cannot be isolated because the compound is in equilibrium with dimethyl ditellurium and tetramethyldiphosphane2. [Pg.197]

Dimethylphosphano-, dimethylarsano-, and dimethylstibanophenyl methyl tellurium reacted with excess methyl iodide in acetone at the P, As, or Sb atom to produce trimethylonium iodides1... [Pg.458]

When methyl 2-X-phenyl tellurium with a dimethylphosphano, dimethylarsano, or dimethylstibano group as ortho substituent was treated with excess methyl iodide in refluxing acetone, only the group-V element was quaternized. Prolonged reflux of the reaction mixture appeared to have caused quaternization of tellurium1. [Pg.684]
