Safety information and MSDS view more

  • Pictogram(s):FlammableF,CorrosiveC

  • Hazard Codes:T,F,C,Xn

  • Signal Word:Danger

  • Hazard Statement:H225 Highly flammable liquid and vapourH301 Toxic if swallowed H312 Harmful in contact with skin H314 Causes severe skin burns and eye damage H331 Toxic if inhaled

  • First-aid measures: General adviceConsult a physician. Show this safety data sheet to the doctor in attendance.If inhaled Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. See Notes. In case of skin contact Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . In case of eye contact First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. If swallowed Rinse mouth. Do NOT induce vomiting. Give nothing to drink. Refer for medical attention . Similar to other silanes. Toxicity is rated high for inhalation, ingestion and local irritation. May cause death or permanent injury after a very short exposure to small quantities. (EPA, 1998) No specific antidote is available /for chlorosilanes/, but first aid treatment consists of copious irrigation with water, & subsequent treatment is as for chemical burns in general. /Chlorosilanes/

  • Fire-fighting measures: Suitable extinguishing media Aqueous film forming foam (AFFF), carbon dioxide, dry sand, special powder. NO hydrous agents. NO water. Violent reaction with water. Toxic and irritating hydrogen chloride and phosgene may be formed in fires. Difficult to extinguish, re-ignition may occur. Flashback along vapor trail may occur. Containers may explode in fire. Vapor may explode if ignited in enclosed area. When heated to decomposition or on contact with acids or acid fumes, chloride fumes are emitted. Reacts with surface moisture, releasing hydrogen chloride, which will corrode common metals and form flammable hydrogen gas. Avoid contact with water; it readily hydrolyzes, liberating hydrochloric acid. Hazardous polymerization may not occur. (EPA, 1998) Wear self-contained breathing apparatus for firefighting if necessary.

  • Accidental release measures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8. Evacuate danger area! Consult an expert! Collect leaking and spilled liquid in sealable dry non-plastic containers as far as possible. Absorb remaining liquid in dry sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer. Personal protection: complete protective clothing including self-contained breathing apparatus. Shut off ignition sources. Call fire department. Avoid contact with liquid. Keep people away. Stop discharge if possible. Isolate and remove discharged material. Notify local health and pollution control agencies.

  • Handling and storage: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2. Fireproof. Separated from food and feedstuffs and other compounds. Cool. Dry. Well closed.Storage temperature; ambient.

  • Exposure controls/personal protection:Occupational Exposure limit valuesBiological limit values Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Eye/face protection Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin protection Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. Respiratory protection Wear dust mask when handling large quantities. Thermal hazards

A General and Selective Synthesis of Methylmonochlorosilanes from Di-, Tri-, and Tetrachlorosilanes

Naganawa, Yuki,Nakajima, Yumiko,Sakamoto, Kei

supporting information, p. 601 - 606 (2021/01/13)

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.

Platinum-Templated Coupling of B=N Units: Synthesis of BNBN Analogues of 1,3-Dienes and a Butatriene

Arrowsmith, Merle,Braunschweig, Holger,Brunecker, Carina,Fantuzzi, Felipe

supporting information, p. 16864 - 16868 (2021/06/28)

The 1:2 reaction of [μ-(dmpm)Pt(nbe)]2 (dmpm=bis(dimethylphosphino)methane, nbe=norbornene) with Cl2BNR(SiMe3) (R=tBu, SiMe3) yields unsymmetrical (N-aminoboryl)aminoboryl PtI2 complexes by B?N coupling via ClSiMe3 elimination. A subsequent intramolecular ClSiMe3 elimination from the tBu-derivative leads to cyclization of the BNBN unit, forming a unique 1,3,2,4-diazadiboretidin-2-yl ligand. In contrast, the analogous reaction with Br2BN(SiMe3)2 leads, via a twofold BrSiMe3 elimination, to a PtII2 A-frame complex bridged by a linear BNBN isostere of butatriene. Structural and computational data confirm π electron delocalization over the entire BNBN unit.
