Price:75000 USD Kilograms
Cooperate with Chinese Academy of Science and Chinese Academy of Engineering, purity of our product≥98%,superior electornic donating ability,long term stable supply.
Appearance: (sensitive to air and water) purple red powder solid
Melting point: 216-220C (lit.)
Storage condition: 2-8 degree C
Purity: ruthenium complex content ≧98%
Purpose: Catalytic decomposition reaction of unsaturated olefins, with a wide range of substrates, Including the requirement for space or the deactivation of olefins, such as 1,1 - Substituted olefins and, α,β - unsaturated carbonyl compounds. The catalytic activity improves the two orders of magnitudethan than the first generation of Grubbs catalyst , the amount of the compound decomposition polymerization in the open loop can be reduced to one in a million. The amount of the complex decomposition reaction is only 5/10000.In some ring closing metathesis reaction in the amount is only five ten thousandths of, especially suitable for the synthesis of low tension cyclic olefins and the larger steric hindrance of multiple substituted olefins.
