Thermolysis of hexakis(2,4,6-triisopropylphenyl)cyclotristannane 1 generates tetrakis(2,4,6-triisopropylphenyl)distannene 3 which can be trapped by various reagents.Addition of phenylacetylene to 3 yields a 1,2-distannacyclobutene derivative.Reaction of 3 with tellurium and selenium leads to tellura- and selenadistanniranes, 7,9, with an excess of these chalcogens the 1,3-dichalcogenadistannetanes, 8, 10, are formed.With elemental sulfur the 1,3-dithiadistannetane 12 along with the 1,2-dithiadistannetane 13 is formed.Thiadistannirane 11, which is not accessible by this route, is, however, smoothly obtained by reaction of 3 with methylthiirane.
