Reactions of 1,2-dihaloethanes with chalcogenide anions generated from elemental chalcogens and dimethylchalcogens were performed in the hydrazine hydrate-KOH system. The use of anions Se x 2- and Te x 2- (x = 1-4) resulted in ethylene evolution and chalcogen regeneration (or in increased x value in an anion). Oligomers of Thiokol type formed only in the reaction of the 1,2-dichloroethane with a mixture of potassium disulfide and diselenide. The reductive cleavage of oligomers obtained in the hydrazine hydrate-KOH system followed by methylation led to the formation of 1,2-bis(methylthio)ethane, 1-methylseleno-2- methylthioethane, and 1,2-bis(methylseleno)ethane. The features of substitution with chalcogenide anions in vicinal dihalides are discussed. Mass spectra of compounds obtained were measured and analyzed. Pleiades Publishing, Inc. 2006.
Reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide

experimental part, p. 988 - 992 (2011/02/26)
The reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide gave ethyltellanyl derivatives as a result of replacement of one chlorine atom in the substrate by tellurium, and of the other, by hydrogen. Probable mechanisms of reduction of the C-Cl bond and mass spectra of the products were considered. The mass spectra of ditelluroacetals revealed unusual rearrangement of the molecular ion, leading to the formation of Te-Te and new C-C bond.

Methods of preparing Group IVA and Group VIA organometallic compounds, particularly Group IVA organometallic compounds, are provided. Such manufacturing methods employ an amine and/or phosphine catalyst in a transalkylation step and may be performed in a batch, semi-continuous or continuous manner.
