Auf Schmetterlingsflügeln getragenDas unsymmetrische luftstabile Disilan Me3Si‐SiMe2[oCON(iPr)2C6H4] bis(silyliert) terminale Alkine hoch regioselektiv und gut verträglich mit funktionellen Gruppen zu Z‐Vinyldisilanen. Z. L. Song et al. beschreiben in ihrer Zuschrift auf S. 4859 eine Umwandlung, die mit herkömmlichen Halogenid‐ oder Methoxy‐substituierten unsymmetrischen Disilanen schwer zu erreichen...
The air‐stable unsymmetrical disilane Me3Si−SiMe2[oCON(iPr)2C6H4] has been developed for bis‐silylation of alkynes. This reagent tolerates a range of functional groups, providing Z‐vinyl disilanes in high yields. It is proposed that the phenyl‐ring‐tethered amide group directs oxidative addition of Pd0 into the Si−Si bond, which might facilitate formation of a six‐membered Pd cycle, generating products...
