Reference of 7181-87-5, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.7181-87-5, Name is 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide, molecular formula is C9H11IN2. In a patent, introducing its new discovery.
The invention concerns an improved method for preparing catalysts for hydrosilylation reactions of compounds with ethylene or acetylene unsaturation (for example olefins or acetylene derivatives), in particular but not exclusively those involving polyorganosiloxanes (POS) bearing Si?H units and POS bearing Si-(ethylene or acetylene unsaturation) units. Said preparation corresponds to the following synthesis (I), wherein: A=B=carbon: T1, T2=cyclohexyl, t-butyl or methyl; T3, T4=H; DVTMS=divinyltetramethylsiloxane; t-BuOK=potassium tert-butylate; T.A=room temperature. The invention is characterised in that it consists in carrying out said synthesis in a single step by bringing together salt (III) above, Karstedt (IV) in the presence of a solvent (V) (THF) and a base (VI) (t-BuOK) at room temperature. 1
