Summary

The synthesis of four-, five-, and six-membered tin-substituted oligosilanes via the reactions of dilithio- or dichloro-substituted V,T-bis(diorganylstannyl)oligo-silanes is reported. Especially, the reactions with the dilithio derivatives allow an easy access towards Si-Sn compounds with additional elements in the ring skeleton. The reaction of a branched dihydrotin oligosilane with lithium diisopropylamide (LDA) and CCU yields a five-membered ring with an exocyclic chlorosilyl substituent. The X-ray structure of a bis(hydridodiorganylstannyl)oligosilanes is also shown.
