Sulfur and selenium diamides are obtained by the reaction of sulfur or selenium chlorides with an aliphatic secondary amine. Polyselanes Sex(NR2)2 (x = 2-4, NR2=morpholinyl x = 4, NR2=piperidinyl) are formed in the reaction of elemental selenium with the boiling amine in the presence of Pb304.19 The acyclic tellurium(II) diamide [Te(NMe2)2]00 (see Figure 1) is prepared by the reaction of TeCl4 with LiNMe2.20... 

Pyrosulphuryl chloride, sulphuryl chloride, thionyl chloride and sulphur monochloride all convert tellurium into the tetrachloride, the reaction proceeding most readily with the last named. In the case of thionyl chloride and sulphur monochloride the product is tellurium dichloride if the tellurium is present in excess.3 With pyrosulphuryl chloride the compound formed is TeCl4.SOs when this is acted upon by dry ammonia the product contains tellurium nitride.4... 

Tellurium Tetrachloride, TeCl4.—When chlorine is passed continually over carefully heated tellurium, the final product is a yellow liquid which solidifies to a crystalline mass on cooling. It can be purified by distillation.10 The chlorine can be replaced by sulphur monochloride,11 or even by sulphuryl chloride or thionyl chloride 12...
