- Synthesis and structural characterization of trans-tactic vinylene-silylene(siloxylene) polymers
-
A new synthetic route to prepare stereoselectively trans-tactic poly[vinylene-silylene(siloxylene)]s via polycondensation of divinyldiorganosilanes and divinyltetraorganodisiloxanes in the presence of [{RuCl2(CO)3}2] as a

- Synthesis of Silacyclohexanones from Divinylsilanes and Allylamines by a Rh-Catalyzed Cyclization
-
An efficient synthesis of silacyclohexanones bearing a variety of silyl substituents has been developed by a [Rh(coe)2Cl]2/PCy3-catalyzed cyclization of divinylsilanes with Jun’s allylamine. The silacyclohexanones can be o

- Fluoride complexation by bidentate silicon Lewis acids
-
Diethynyldiphenylsilane (1) and divinyldiphenylsilane (2) were functionalized by hydrosilylation reactions with HSiMe2Cl, HSiMeCl2 and HSiCl3. Fluorination of the resulting compounds generates bidentate open-chain Lewis ac

- Diphenylsilyldiethylene- (DPSide-) group: A new primary amine protection
-
Diphenylsilydiethylene- (DPSide-) group has been developed as a new primary amine protecting group. The new protecting group exhibits novel orthogonality against other commonly used amine-protecting groups and excellent chemoselectivity for unbranched α-amino acid esters. Removal of this protecting group was effected under mild fluoride-based cleavage conditions.

- Towards 2-silaallenes: Synthesis of spirocyclic precursors
-
Reactions of dichlorodivinylsilane(2) and Li/Bu in a molar ratio 1/1 and 12 lead to highly reactive intermediates, which can be trapped by suitable reagents. In the presence of trimethylmethoxysilane, norbornadiene, anthracene and dipheylacetylene, products are formed that provide evidence for the intermediate formation of both the neopentylsilene H2C=CH(Cl)Si=CHCH2tBu (3) and the 2-silaallene tBuCH2CH=Si=CHCH2tBu(4). The formation of double cycloadducts from 4 is particularly interesting as a preparatively facile route for the synthesis of silaspirocycles such as 13, 16 and 17, which have been characterized by single-crystal X-ray structure analysis.
