  • Patent number: 9676679
    Abstract: The present disclosure is directed to a traceless directing group in a radical cascade. The chemo- and regioselectivity of the initial attack in skipped oligoalkynes is controlled by a propargyl alkoxy moiety. Radical translocations lead to the boomerang return of radical center to the site of initial attack where it assists to the elimination of the directing functionality via ?-scission in the last step of the cascade. In some aspects, the reaction of the present invention is catalyzed by a stannane moiety, which allows further via facile reactions with electrophiles as well as Stille and Suzuki cross-coupling reactions. This selective radical transformation opens a new approach for the controlled transformation of skipped oligoalkynes into polycyclic ribbons of tunable dimensions.

  • Patent number: 6255515
    Abstract: An alkali metal- or alkali earth metal-containing organic compound (i) is reacted with a leaving group- and silicon- or germanium-containing compound (ii) in the presence of a nitrogen-containing aromatic heterocyclic compound. By such a method, it is possible to produce a silicon- or germanium-containing organic compound, for example, a cyclopentadienyl compound cross-linked by a silicon atom or a germanium atom, typically a cyclopentadienyl compound which is substituted with a substituted or unsubstituted silyl or germyl group, for a short time with a high yield.
