Muller, Daniel S. published the artcileIn Situ Generation of Ru-Based Metathesis Catalyst. A Systematic Study, Name: 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride, the publication is ACS Catalysis (2019), 9(4), 3511-3518, database is CAplus.
A systematic study for the in situ generation of Ru-based metathesis catalysts was described. Assembly of com. available and inexpensive reagents [Ru(p-cymene)Cl2]2, SIPr·HCl, and n-BuLi led to the formation of 18 electron arene-ruthenium complexes that, in the presence of additives such as alkynes, cyclopropenes, and diazoesters, generated highly selective and efficient catalytic systems applicable to a variety of olefin metathesis transformations. Notably, we were able to achieve a productive TON of 4500 for the self-metathesis of Me oleate, a reaction which could be easily upscaled to 2 kg.
