Synthesis and coordination ability of a partially silicon based crown ether

The first hybrid crown ether with two adjacent disilane fragments was synthesized through reaction of O(Si2Me4Cl)2 (3) with O(C2H4OH)2. By means of DFT calculations, the complexation ability of 1,2,4,5-tetrasila[12]crown-4 (7) towards Li+ was determined to be considerably higher compared to [12]crown-4.

Hydrogen-Bridged Oligosilanylsilyl Mono- and Oligosilanylsilyl Dications

Hydrogen-bridged oligosilanylsilyl borates 8 [B(C6F5)4], 9[B(C6F5)4] and diborates 10 [B(C6F5)4]2 have been prepared by hydride transfer between α-ω-dihydrido- (11) and branched tetrahydrido-oligosilanes (13) and trityl cation. The obtained cyclic intramolecularly stabilized silylium ions 8, 9 and bissilylium ion 10 were characterized by low temperature NMR spectroscopy supported by the results of density functional calculations. The branched Si?H?Si monocation 9 undergoes at low temperatures a fast degenerate rearrangement, which exchanges the Si?H groups with a barrier of 31 kJ mol?1 via an antarafacial transition state. Reaction of the branched monocation 9 with a second equivalent of trityl cation or of the branched oligosilane 13 with two equivalents of trityl cation, gives at ?80 °C the corresponding bissilylium ion 10, an example for a new class of highly reactive poly-Lewis acids.

London dispersion-driven hetero-aryl-aryl interactions in 1,2-diaryldisilanes

Non-covalent aryl-aryl interactions for the molecular structures of three 1,2-diaryltetramethyldisilanes X5C6-(SiMe2)2-C6Y5 (X ≠ Y; X, Y = H, F, Cl) were studied by single crystal X-ray and

Rhodium-Catalyzed Intermolecular trans-Disilylation of Alkynones with Unactivated Disilanes

Disilylation of alkynes could provide rapid entry to synthetically useful 1,2-bissilyl-alkenes, but is currently limited to activated disilanes reacting in an intramolecular fashion. Reported herein is an efficient rhodium(I)-catalyzed intermolecular disi

Ruthenium-catalyzed alkoxylation of a hydrodisilane without Si[sbnd]Si bond cleavage

Transition metal-catalyzed synthesis of alkoxydisilanes via dehydrogenative coupling of a hydrodisilane with alcohols is reported. During the reaction, the Si[sbnd]Si bond is preserved effectively when [RuCl2(p-cymene)]2is used as a catalyst. Various alcohols can be used in this alkoxylation.

Activator-free palladium-catalyzed silylation of aryl chlorides with silylsilatranes

The palladium-catalyzed silylation of aryl chlorides with silylsilatranes proceeds under activator-free conditions; hence, wide functional group compatibility is displayed and boryl and siloxy groups are able to survive. Experimental and computational stu

Stereoselective intramolecular bis-silylation of alkenes promoted by a palladium-isocyanide catalyst leading to polyol synthesis

Details of a study on the intramolecular bis-silylation of terminal alkenes promoted by a palladium-tert-alkyl isocyanide catalyst are described. With a disilanyl ether derived from a homoallylic alcohol, intramolecular regioselective addition of the Si-Si linkage to the C=C bond took place to furnish an exo-ring closure product, i.e., 1,2-oxasilolane. The bis-silylation of alkenes having substituents α to the C=C bond gave trans-3,4-disubstituted oxasilolanes, while substitution β to the C=C bond favored cis-3,5-disubstituted oxasilolanes. The stereoselectivity trends are formulated as arising from a preference for a chairlike transition state over a boatlike one. A substituent, either a or β to the C=C bond, prefers the equatorial position in a chairlike transition state. The 1,2-oxasilolanes thus produced stereoselectively were oxidatively converted to the corresponding 1,2,4-triols. The present methodology for the synthesis of 1,2,4-triols was successfully extended to the stereoselective synthesis of 1,2,4,5,7- and 1,2,4,6,7-pentaols through a sequence of intramolecular bis-silylations. The bis-silylation was also performed with alkenes linked to disilanyl groups through a three-carbon chain and through an amide linkage. Stereoselections analogous to those of the ether substrates were observed. Alkenes tethered to disilanyl groups through chains of two atoms underwent similar intramolecular bissilylation. In conclusion, the intramolecular bis-silylation of C=C bonds followed by oxidation constitutes a new synthetic transformation equivalent to the stereoselective dihydroxylation of olefins.
