dimesitylneopentylsilene Mes2Si CHCH2tBu 1 is obtained in almost quantitative yield by reaction of tert-butyllithium with dimetisylvinylfluorosilane 4; 1 is certainly one of the most easily available stable silenes. In spite of its stability, 1 presents a high reactivity in the field of classical chemistry of organometallic alkenes such as addition or cycloaddition reactions and, in some cases, an original behaviour

TCNE photo-sensitized decompositions of oxasilacyclopropane (1) generated carbene and silanone, while the DCA sensitized or direct photolysis of (1) gave silylene and indanone.

The outcome of the controlled potential oxidation and reduction of a disilene, tetramesityldisilene (TMDS), indicates that the main silicon containing products involve only one silicon atom and have the general structure Mes2SiX(Y), X and Y being H, OH or F.
对一种二硅烯--四甲基二硅烯(TMDS)进行受控电位氧化和还原的结果表明,主要的含硅产物只涉及一个硅原子,其一般结构为 Mes2SiX(Y),X 和 Y 分别为 H、OH 或 F。

Geo‐inspired activation: The first example of silanediolsactivating amide and aldehyde substrates through hydrogenbonding is described. Both NMR and X‐ray co‐crystallization studies demonstrate binding modes and affinity, and show that silanediolhydrogen‐bonding assemblies can be modulated by the addition of carbonylcompounds. These silanols show catalysis in a Diels–Alder reaction and provide
