资源简介：
The NHC-supported silylaminosilylene Ar(SiMe3)N(Cl)Si(IiPr) (1; Ar = 2,6-iPr2C6H3, IiPr = 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene)
is an efficient and stereospecific bis-silylation reagent for a range
of functionalized alkynes to yield cis-1,2-bis-silylated alkenes via
a 1,4-silyl migration from the amino nitrogen atom to an alkyne carbon
atom. The reaction is regio- and stereospecific for terminal alkynes
with an electron-withdrawing substituent, thus providing a facile
access to 1,2-bis-silylated alkenes with two different silyl groups.
