Building blocks for oligomeric siloxanes –selective chlorination of hydrido-siloxanes

A new method was developed to achieve highly selective monochlorination of α,ω-dihydridosiloxanes, ((H)Me2SiO-(SiMe2O)n-SiMe2(H), n = 0–2; (H)R2Si–O-SiR2(H); R = Me, iPr, Ph; 3,5-dihydridooctamethyltetrasiloxane, Me3SiO-(Si(H)MeO)2–SiMe3) with trichloroisocyanuric acid (TCCA). The dependence of the selectivity of the monochlorination on the siloxane chain length is also discussed.

POLYARYLACETYLENES CONTAINING SILOXANE, SILANE, AND CARBORANE MOIETIES

Disclosed herein are the compounds shown below. Each R is an organic group, Cb is a carborane group, and —C6H4— is phenylene. The value of each m is a nonnegative integer, q is 0 or 1, with the proviso that if q is 0 then m is 0 or 1, p is a positive integer, r is a positive integer, and n is an integer greater than or equal to 10. Also disclosed are methods of making and crosslinking the compounds.

REACTION OF ALLYL HALIDES WITH DIMETHYLPHENYLSILANE AND HEXAMETHYLTRISILOXANE IN THE PRESENCE OF HEXACHLOROPLATINIC ACID

The reaction of dimethylphenylsilane with allyl chloride yields γ-chloropropyldimethylphenylsilane and dimethylphenylchlorosilane, whereas that with allyl bromide results in dimethylphenylbromosilane only.Hydrosilylation of allyl halides with 1,1,3,3,5,5-hexamethyltrisiloxane yields a mixture of various symmetric and asymmetric adducts at both Si-H bonds of the trisiloxane.

Lanthanocene (Ln = PrIII, YbIII) chlorides involving tetramethyldisiloxane-interlinked cyclopentadienyl ligands

Two new lanthanocenophanes PrIIICl*THF>x (2; x=1 or 2) and YbIIICl>2 (3), were made from LnCl3 (Ln=Pr or Yb) and K2 in THF.The 1H NMR spectra of THF-d8 solutions of paramagnetic 2 (at +35 to -25 deg C) and 3 (at 8 (at > 10 deg C), respectively, display somewhat less complex 1H NMR spectra consistent with a virtually symmetrical position of the Me2SiOSiMe2 unit with respect to the cent-Ln-cent' plane (cent = C5H4Si centroid).A low temperature (-100 deg C) single-crystal X-ray study of 3 has confirmed the presence of centrosymmetric, Cl-bridged dimers in which the molecular configuration of the mononuclear YbIIICl2 units correspond to that of the previously described complex IVCl2> (1).The high-resolution mass spectrum of 3 displays several signals from dinuclear fragments, the B/E-linked scans of which suggest, inter alia, intramolecular reorientation of at least one O(Me2SiC5H4)2 ligand from the chelating into a metal-bridging position.Key words: Ytterbium; Praseodymium; Metallocenes; Lanthanides; Chiral metallocenophanes; Crystal structure

GAS-PHASE REACTIONS OF (BENZYLOXY)TRICHLOROSILANE WITH HEXAMETHYLCYCLOTRISILOXANE AND OCTAMETHYLCYCLOTETRASILOXANE

Dichlorosilanone generated by the pyrolysis of (benzyloxy)trichlorosilane in the temperature range 500-620 deg C is inserted in a specific way into an Si-O bond in the cyclosiloxanes D3 and D4 with the formation of new cyclosiloxanes containing functional SiCl2 groups.

REACTION OF OCTAMETHYLCYCLOTETRASILOXANE AND PERMETHYLOLIGOSILOXANES WITH ACYL CHLORIDES IN THE PRESENCE OF CoCl2

Octamethylcyclotetrasiloxane is cleaved quantitatively by acetyl chloride (1:1 molar ratio) in the presence of anhydrous CoCl2 in acetonitrile at room temperature to form primarily α-chloro-ω-acetoxyoligodimethylsiloxanes nOCOCH3 (n = 0-3; yield, 60-65percent)>.In the presence of an equimolar amount of trimethylacetoxysilane of hexamethyldisiloxane, the major reaction products are α-methyl-ω-acetoxyoligodimethylsiloxanes nOCOCH3 (n = 4-6; yield, 65-70percent)>.

A Convenient Synthesis of α,ω-Difunctionalized Linear Dimethylsiloxanes with Definite Chain Lengths

α,ω-Difunctionalized linear dimethylsiloxanes with definite chain lengths are conveniently prepared by the inorganic-solid-catalyzed ring cleavage of cyclodimethylsiloxanes with dimethylchlorosilane and water under very mild conditions.
