  Reactions of an isolable dialkylsilylene with dichloromethane and (chloromethyl)cyclopropane occur in solution to afford the double silylene insertion product and an unusual 5-silaspiro[4.4]nonane derivative, respectively. The activation of the carbon–chlorine bonds due to the complexation of haloalkanes with the silylene may facilitate the nucleophilic attack of another silylene under the present

  element congeners of allene (heavy allenes) [R(2)M=M'=MR(2); M = M' = Si (1a), M = Si, M' = Ge (1b), M = Ge, M' = Si (1c), and M = M' = Ge (1d)] are comparatively discussed. Using DFT calculations and PMO theory, the origin of the bent and fluxional skeleton of the heavy allenes is ascribed to the Jahn-Teller distortion associated with the effective pi-sigma* mixing (pi-sigma* distortion). This type of distortion

• Reactions of trisilaallene and 2-germadisilaallene with various reagents

  A number of the distinctive reactions of trisilaallene 1 and 2-germadisilaallene 4 with various reagents including water, alcohols, acetone, and haloalkanes were studied. The addition reactions of 1 to water and alcohols occur in a regiospecific manner to afford 1,3-dioxytrisilanes in high yields. The additions are explained by a stepwise mechanism involving the initial nucleophilic attack of a hydroxy oxygen to a terminal allenic silicon to give an intermediate unsymmetric disilene. The regiospecificity is rationalized by the shape of the frontier molecular orbitals and the NPA charge distribution of trisilaallene 1 and the intermediate disilene. (c) 2006 Elsevier B.V.
