Chloro (methyl) silane is a chemical compound from the class of the silanes . It consists of a central silicon atom around which two hydrogen atoms and one chlorine atom and one methyl radical are coordinated in a tetrahedral manner .
presentation
Chlorine (methyl) silane can be produced by the chlorination of methylsilane with hydrogen chloride in the presence of aluminum chloride as a catalyst at an elevated temperature. Dichloro (methyl) silane is formed as a by-product .
properties
It is a compound that is gaseous at room temperature, liquefies at −46 ° C (at 13 hPa) and solidifies at −135 to −134 ° C.
use
Chlorine (methyl) silane can be used to produce organic silanes. The chlorine substituent serves as a leaving group and can be exchanged for nucleophiles in a substitution reaction . Grignard compounds or organolithium compounds , for example, can be used as nucleophiles .
