S-Heterocyclic Carbene with a Disilane Backbone

S-Heterocyclic Carbene with a Disilane Backbone

Caught in a trap! An S‐heterocyclic carbene (SHC) with a cyclotetrasilane backbone is generated by a [2+3] cycloaddition of cyclotetrasilene with CS2 and trapped with C60 as a chemical probe. It is demonstrated that photolysis of anti‐dodecaisopropyltricyclo[4.2.0.02,5]octasilane and CS2 in the pres...

Zusammenfassung:Caught in a trap! An S‐heterocyclic carbene (SHC) with a cyclotetrasilane backbone is generated by a [2+3] cycloaddition of cyclotetrasilene with CS2 and trapped with C60 as a chemical probe. It is demonstrated that photolysis of anti‐dodecaisopropyltricyclo[4.2.0.02,5]octasilane and CS2 in the presence of C60 affords a methanofullerene (see scheme).
