Ruthenium, the preparation method of dichloro[[2-(1-Methylethoxy-κO)-5-nitrophenyl]Methylene-κC](tricyclohexylphosphine)-, (TB-5-23)-is generally as follows:
1. first, RuCl2(PCy3)2(dichlorobis(tricyclohexylphosphine)ruthenium(II)) is reacted with 2-(II) = 2 Methylene to generate RuCl2(PCy3)(CHPh)(OCHMeCH3NO2), I .e. Ruthenium, dichloro [1-(1-methyllethoxy-o)-5-nitrophenyl]Methylene-κC](tricyclohexylphosphine)-precursor of ligand. 23-, (TB-5).
2. Then, the ligand precursor is reacted with a base (such as sodium carbonate) to produce Ruthenium, dichloro[[2-(1-Methylethoxy-κO)-5-nitrophenyl]Methylene-κC](tricyclohexylphosphine)-, (TB-5-23)-.
About safety information:
1. Ruthenium, dichloro[[2-(1-Methylethoxy-κO)-5-nitrophenyl]Methylene-κC](tricyclohexylphosphine)-, (TB-5-23)-may adhere to moisture and lose catalytic activity in humid air, so it needs to be stored in a dry environment.
2. Due to Ruthenium, dichloro[[2-(1-Methylethoxy-κO)-5-nitrophenyl]Methylene-κC](tricyclohexylphosphine)-, (TB-5-23)-contains toxic substance Ruthenium (Ruthenium), which should comply with the safe operation specification of chemical laboratory when using and disposing.
3. For those who may come into contact with Ruthenium, dichloro[[2-(1-Methylethoxy-κO)-5-nitrophenyl]Methylene-κC](tricyclohexylphosphine)-, (TB-5-23)-, they should wear appropriate personal protective equipment, such as gloves and goggles, to avoid direct contact with skin and eyes.
Although Ruthenium, dichloro[[2-(1-Methylethoxy-κO)-5-nitrophenyl]Methylene-κC](tricyclohexylphosphine)-, (TB-5-23)-is relatively safe under laboratory conditions, it is still recommended to carefully read relevant safety materials and operating guidelines before use.
