Synthesis of Tin-Containing Heterocyclic Compounds by the Reaction of 1,3,5,2,4,6-Trichalcogenatristannin with 1,3-Dipoles

Abstract

Reaction of 1,3,5,2,4,6-trithiatristannin with 2,4,6-tri-t-butylbenzonitrile oxide gave the 1,3,5,2-oxathiazastannole quantitatively. Reaction of 1,3,2,4-dithiadistannetane with 2,4,6-tri-t-butylbenzonitrile oxide also quantitatively but slowly afforded the 1,3,5,2-oxathiazastannole. Reaction of 1,3,5,2,4,6-triselenatristannin with 2,4,6-tri-t-butylbenzonitrile oxide gave 1,3,5,2-oxaselenazastannole. The thermal behavior of the oxaselenazastannole was unusual.
