A new strategy for the synthesis of homologously pure linear polystannane oligomers
摘要:
The reagent 6 is utilized for the stepwise synthesis of linear polystannane oligomers in which hydrostannolysis is employed as the Sn-Sn bond-forming reaction, and DIBAL-H is used to regenerate a new Sn-H functionality for extended chain growth through repetition of the two-step reaction sequence. The electronic spectra of these oligomers are influenced by chain length and the specific placement of substituents, as demonstrated by the homologous series 7, 9, and 13-15 and the phenylated di- and tristannanes 18-20.
