Direct catalytic transformation of chlorosilanes into organosilicon compounds remains challenging due to difficulty in cleaving the strong Si-Cl bond(s). We herein report the palladium-catalyzed cross-coupling reaction of chlorosilanes with organoaluminum reagents. A combination of [Pd(C3H5)Cl]2 and DavePhos ligand catalyzed the selective methylation of various dichlorosilanes 1, trichlorosilanes 5, and tetrachlorosilane 6 to give the corresponding monochlorosilanes.

Four triphenylene (TP) and four hexa-peri-hexabenzocoronene (HBC) derivatives with trialkylsilylethynyl groups were prepared and characterized by differential scanning calorimetry, polarizing optical microscopy, and X-ray diffraction measurements. All compounds were highly soluble in less-polar organic solvents and exhibited a columnar phase, Colh or Colr for the TPs, and Colh for the HBCs. The hole transport ability in the HBCs' columnar phase, 0.4-1.5×10-3 cm2 V-1 s-1 at 40-180°C, and its temperature dependence were determined by the time-of-flight method using a solution technique.
Method for producing chlorosilanes
-
, (2008/06/13)
A method for producing chlorosilanes, which are useful in a wide range of industrial field as an intermediate for organosilicon products such as silicone rubbers, silicone oils, silicone resins, etc. as well as a raw material for the production of organic chemicals such as medicines, agricultural chemicals, dyestuffs, etc., represented by the general formula, STR1 wherein R1 and R4, which may be the same or different, represent an alkyl group having from 1 to 5 carbon atoms, a chloromethyl group, an ethynyl group or a halogen atom; R2 and R3, which may be the same or different, represent an alkyl group having from 1 to 3 carbon atoms; R5 and R6, which may be the same or different, represent an alkyl group having from 1 to 2 carbon atoms; and R7 represents an alkyl group having from 1 to 18 carbon atoms, which comprises reacting a disiloxane represented by the general formula, STR2 wherein R1, R2, R3, R4, R5 and R6 are as defined above, or a silanol represented by the general formula, STR3 wherein R2, R3 and R7 are as defined above, with phosgene in the presence or absence of a tertiary amide.
246. Monofunctional (Dimethylamino)silane as Silylating Agent

, p. 2128 - 2142 (2007/10/02)
The reaction of triorganyl(dimethylamino)silanes with surface-hydrated silicon dioxide has been studied.These silylating agents are easy to prepare from the corresponding chloro or bromosilanes with dimethylamine.The resulting products are thermally stable and relatively volatile.Reaction with surface-hydrated silicon-dioxide preparations at a50-250 deg C for 170 h yields a dense grafted layer.However, with (dimethylamino)silanes having strongly polar substituents, a retreatment of the surface-modified silica seems to be necessary in order to attain maximum coverage.
