From Alkoxy Tellurium IV Chlorides

Bis[morpholino] tellurium dichloride was also obtained from bis[tetrafluoropropoxy] tellurium dichloride or tris[tetrafluoropropoxy] tellurium chloride and iV-trimethylsilyl-morpholine.  

Bis[morpholino] Tellurium Dichloride To a stirred solution of 1.38 g (3 mmol) of bis[2,2,3,3-tetrafluoropropoxy] tellurium dichloride in 20 ml of anhydrous diethyl ether at 0° is added dropwise a solution of 1.03 g (6.5 mmol) of Af-trimethylsilylmorpholine in 10 ml of diethyl ether. The mixture is stirred at 5° for 1 h. The precipitate is filtered and washed with diethyl ether yield 80%.
