- Synthesis and structure of the donor-free potassium silanide K[SiPh3]
-
The donor-free potassium silanide K[SiPh3] was prepared by the reaction of hexaphenyldisilane, Ph3Si-SiPh3, with potassium metal in benzene at room temperature. The solid-state structure, determined by powder X-ray diffrac

- Boron-metal exchange reaction of silylboranes with organometallic reagents: A new route to arylsilyl anions
-
The boron-metal exchange reaction of (arylsilyl)boranes with alkyllithiums, potassium tert-butoxide, and methylmagnesium bromide affords the corresponding silyllithium, silylpotassium, and silylmagnesium compounds, respectively. Especially, the boron-lithium exchange reaction occurs even in hydrocarbon solvents such as toluene and hexane as well as in THF.

- Carbanion mechanisms XVIII. Generation of silyl anions by nucleophilic cleavage of disilanes
-
Organosilyl potassium compounds are conveniently generated by cleavage of hexaorganodisilanes with potassium t-butoxide in common solvents other than HMPA (i.e. in THF or DME).Nucleophilic attack on unsymmetrical disilanes results in formation of the more

- Les triorganosilylpotasium: nouvelle voie d'acces et quelques aspects de leur reactivite
-
We report here a new procedure for the convenient and easy preparation of silylanions and especially of Me3Si-.These undergo coupling reaction with halides and α-enone in good yields.Reactions with 5-bromo-1 hexene, benzophenone and carbon dioxide provide evidence for the ability of the silylpotassium to act as monoelectron transfer reagents.The course of these reactions varies substantially with the nature of the solvent.

- PHOTOINDUCED ELECTRON TRANSFER FROM TRIPHENYLMETHYL ANION OR TRIPHENYLSILYL ANION TO p-TERPHENYL
-
The steady illumination of triphenylsilyl anion and p-terphenyl (p-TP) in tetrahydrofuran yielded the radical anion of p-terphenyl (p-TP.-), which persisted after cutting of the light.When the triphenylmethylanion was used, p-TP.- wa
