  摘要：

  Treatment of chlorobis(2,4,6-triisopropylphenyl)silane (Ar2SiHCl) with lithium naphthalenide and subsequent,addition of the chlorosilanes R2SiHCl (R =(i)Pr, (t)Bu, Mes) gives the unsymmetrical disilanes R2HSiSiHAr2 which are smoothly converted into the 1,2-dichlorodisilanes 8-10. The X-ray structure analysis of the 1,1-dimesityldisilane 10 reveals a staggered conformation with the chlorine atoms disposed in an anti orientation. Whilst the reductive chloride elimination from the 1,1-dialkyldichlorodisilanes 8 and 9 did not give the corresponding disilenes, the same reaction of 10 provided bright yellow crystals of 1,1-dimesityl-2,2-bis(2,4,6-triisopropylphenyl)disilene, the structure of which was confirmed by a complete NMR study.

  Well‐shuffled: An unexpected substituent distribution reaction via alkyldiarylsilylium ions leads to a distribution of substituents. Starting from alkyldiaryl silanes, this reaction provides a facile synthetic approach to sterically highly hindered triarylsilylium ions. These silylium ions can be applied in dihydrogen activation reactions.
