Description

technical field [0001] The present invention relates to a method for synthesizing organic matter in the field of organic chemistry, in particular to a liquid-phase synthesis of organosilicon realized by the dehydrosilylation reaction of alcohol or phenol with hydrosilane under the catalysis of manganese carbonyl metal organic compounds ether method. Background technique [0002] Silicone monomer is a new type of high-tech material. Because of its small amount of direct use but wide application, it is known as "industrial monosodium glutamate". Its use has been developed from being a special material in aviation, cutting-edge technology, and military technology departments to the national economy such as construction, electronics, textiles, automobiles, machinery, leather and paper, chemical light industry, metals and paints, medicine and medical treatment. in various fields. Organosilicon ether, also known as oxysilane, is an important part of the silicone monomer family. ...
