  Reactions of chloromethyl heptyl ether with selenium and tellurium in the system hydrazine hydrate-potassium hydroxide

  摘要：

  Chloromethyl heptyl ether reacts with selenium in the system hydrazine hydrate-potassium hydroxide with formation of a mixture of bis(heptyloxymethyl)selane (32%) and bis(heptyloxymethyl)diselane (64%). Reductive cleavage of the latter with hydrazine hydrate-KOH and subsequent alkylation with methyl iodide gave methyl(heptyloxymethyl) selane in 94% yield. Analogous reaction of tellurium with hydrazine hydrate-KOH leads to the formation of extremely unstable bis(heptyloxymethyl) ditellane and bis(heptyloxymethyl) tellane at a ratio of 1 : 4.

  Two approaches to synthesis of bis-chalcogenyl derivatives of propene with two different chalcogen atoms are proposed. Reaction of 2,3-dichloro-1-propene with two different chalcogen nucleophiles PhY- (Y = S, Se) results in a mixture of two products with two identical chalcogen atoms and two products with different ones. The reactivity of PhY- anions under the reaction conditions (60A degrees C) practically does not depend on the Y nature. Reaction of anions RY- (Y = S, Se, Te) with the products of the reaction of 2,3-dichloro-1-propene and organic chalcogenides in the hydrazine hydrate-alkali medium affords the target unsaturated chalcogen-containing compounds with two different chalcogen atoms, 1,2-bis(organylchalcogenyl) propenes in up to 73% yield.

  Dimethyldiselenide reacts with 2,3-dichloro-1-propene at 20-25A degrees C in the hydrazine hydrate-KOH medium to form 2-chloro-3-methylselanyl-1-propene with 90% yield. Diphenyldiselenide in the reaction with 2,3-dichloro-1-propene, depending on the conditions, can give quite selectively four products: 2-chloro-3-phenylselanyl-1-propene, phenylselanylpropadiene, 1-phenylselanyl-1-propyne, and Z-1,2-bis(phenylselanyl)-1-propene. The effect of the selenium atom on the reaction direction and the products structure is discussed.
