From Dimorpholino Tellurium Difluorides

Although it has not been possible to replace the fluorine atoms in bis[dialkylamino] tellurium difluorides by dialkylamino groupsS the fluorine atoms in dimorpholino tellurium difluoride did react with A,A-bis[trimethylsilyl]arenesulfonamides to form arenesulfonimino dimorpholino tellurium derivatives.  

Benzcnesulfonimino Dimorpholino Tellurium 3.38 g (10 mmol) of bis[morpholino] tellurium difluoride are suspended in 40 ml of anhydrous benzene, the suspension is stirred, and a solution of 3.3 g (11 mmol) of M,N-bis[trimethylsilyl]benzenesulfonamide in 20 ml of benzene is added. The mixture is stirred until all the solid has dissolved and then allowed to stand for 10 h. The precipitated crystals are filtered, washed with diethyl ether, and recrystallized from benzene yield 4.4 g (96%) m.p. 114°. 

Arenesulfonimino tellurium difluorides and A-trimethylsilylmorpholine reacted at 20° to form arenesulfonimino dimorpholino tellurium derivatives.  

Bis jiuoroalkoxy dimorpholino tellurium compounds were prepared from bis[fluoro-alkoxy] tellurium difluoride or tetrakis[fluoroalkoxy] tellurium compounds and two molar equivalents of A7-trimethylsilylmorpholine in a medium of diethyl ether at 5 .
