Introduction
cis,cis-1,3-cyclooctadiene (cis,cis-1,3-cyclooctadiene) is an organic compound with the chemical formula C8H12. It has two conjugated double bonds and an eight-membered ring structure.
cis,cis-1,3-cyclooctadiene is a colorless liquid with a special fragrance. It can be dissolved in common organic solvents, such as ethanol, tetrahydrofuran and dimethylformamide.
in chemistry, cis,cis-1,3-cyclooctadiene are often used as ligands of coordination compounds to participate in the synthesis of transition metal compounds such as platinum and molybdenum. It can also act as a catalyst precursor in the hydrogenation of unsaturated compounds. In addition, cis,cis-1,3-cyclooctadiene can also be used as synthetic intermediates of dyes and fragrances.
cis,cis-1,3-cyclooctadiene mainly has two preparation methods: one is through photochemical reaction, that is, 1,5-cycloheptadiene is exposed to ultraviolet light, and cis,cis-1,3-cyclooctadiene is generated through reaction. Another method is by metal catalysis, for example by reaction with a metal catalyst such as palladium, platinum, etc.
Regarding the safety information of cis,cis-1,3-cyclooctadiene, it is a flammable liquid with flammable characteristics in the form of steam or gas. During use and storage, care should be taken to avoid contact with open flames, high temperatures and oxygen. At the same time, contact with the skin, eyes and respiratory tract of cis,cis-1 and 3-cyclooctadiene may cause irritation and damage. Therefore, protective gloves and goggles should be worn when using, and a well-ventilated working environment should be maintained.
