- Palladium-Catalyzed β-Elimination of Aminoboranes from (Aminomethylsilyl)boranes Leading to the Formation of Silene Dimers
-
Silylboronic esters bearing a N,N-dialkylaminomethyl group on the silicon atoms were synthesized and used in palladium-catalyzed reactions. Five silylboronic esters were synthesized through a reaction of the [(N,N-dialkylaminomethyl)diorganosilyl]lithiums

- Highly diastereoselective intramolecular Diels-Alder reaction of chiral silatrienes
-
New Si-chiral 2-silahexa-3,5-dienyl acrylates were prepared in six steps from dichloro(chloromethyl)methylsilane. The EtAlCl2 catalysed intramolecular Diels-Alder reaction of these compounds gave chiral 4-sila-4a,7,8,8a-tetrahydroisochroman-1-ones in good yield. Very good diastereoselectivity was observed for a silatriene bearing a methyl and a 2-methoxyphenyl substituent on the chiral silicon atom.

- Diastereoselective synthesis of 4-sila-3,4,4a,5-tetrahydro-2H-isoquinolin-1-ones through intramolecular Diels-Alder reaction of chiral silatrienes
-
New Si-chiral N-2-silabut-3-enylpyran-2-one-6carboxamides were prepared in four steps from dichloro(chloro-methyl)methylsilane. The thermal inverse electron demand intra-molecular Diels-Alder reaction of these compounds gave 4-sila3,4,4a,5-tetrahydro-2H-isoquinolin-1-ones. Moderate diastereoselectivity was observed for a silatriene bearing a methyl and a cyclohexyl substituent on the chiral silicon atom. The intermediate tricyclic adduct of this reaction was also isolated.

- SILAETHENE II. DARSTELLUNG UND CHARAKTERISIERUNG VON 1,3-DISILACYCLOBUTANEN
-
1,3-Disilacyclobutanes of the types R1R2SiSiR1R2 are prepared (a) by ring synthesis from chloromethylchlorosilanes R1R2Si(CH2Cl)Cl, (b) by thermolysis of monosilacyclobutanes , and (c) by substitution of chlorine with alkyl groups in SiCl-containing 1,3-disilacyclobutanes, obtained by procedures (a) or (b).The compounds have been characterized by analytical and spectroscopic investigations.The synthetic methods are critically compared.
