Ozer, Halenur; Arslan, Dilan; Ozturk, Bengi Ozgun published an article in 2021. The article was titled 《Dehydrogenative alcohol coupling and one-pot cross metathesis/dehydrogenative coupling reactions of alcohols using Hoveyda-Grubbs catalysts》, and you may find the article in New Journal of Chemistry.Application In Synthesis of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium The information in the text is summarized as follows:
In this study, in situ formed ruthenium hydride species that were generated from Grubbs type catalysts are used as efficient catalysts for dehydrogenative alc. coupling and sequential cross-metathesis/dehydrogenative coupling reactions. The selectivity of Grubbs first generation catalysts (G1, I) in dehydrogenative alc. coupling reactions can be tuned for the ester (octyl octanoate) formation in the presence of weak bases, while the selectivity can be switched to the β-alkylated alc. (2-hexyyl-1-decanol) formation using strong bases. The performance of Hoveyda-Grubbs 2nd generation catalyst (HG2) was improved in the presence of tricyclohexylphosphine for the selective synthesis of ester derivatives RC(O)OR1 (R = heptyl, Ph, dec-9-en-1-yl, etc.; R1 = H, octyl, Bn, etc.) and with γ-butyrolactone weak and strong bases in quant. yields. Allyl alc. was used as self and cross-metathesis substrate for the HG2 catalyzed sequential cross-metathesis/dehydrogenative alc. coupling reactions to obtain γ-butyrolactone and long-chain ester derivatives in quant. yields. After reading the article, we found that the author used Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Application In Synthesis of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium)
Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is a ruthenium-based olefin metathesis catalyst. It is useful for olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions, and so on.Application In Synthesis of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
