Triple ring closing metathesis reaction : synthesis of adjacent cyclic ethers [PDF]
, 2001 Adjacent tris(cyclic ethers) and enol ethers have been synthesized in good yields for the first time via a triple olefin metathesis reaction using Grubbs' catalyst RuCl2(double bondC(H)Ph)(PCy3)(2) (Cy = cyclohexyl), and the 1,3-dimesitylimidazol-2 ...

Construction of Fluorinated Amino Acid Derivatives via Cobalt-Catalyzed Oxidative Difunctionalization of Cyclic Ethers [PDF]
, 2022 Via difunctionalization of the α- and β-sites of cyclic ethers, we herein demonstrate a new synthetic method for the efficient construction of novel fluorinated γ-amino acid esters by employing a CoBr2/m-CPBA catalyst system.

Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Stereoselective alkene syntheses from cyclic enol ethers [PDF]
, 1988 Two novel methods for the stereoselective synthesis of trisubstituted olefins from cyclic enol ethers were investigated. The first utilised the nickel (O)-catalysed coupling reactions of α-alkyl substituted cyclic enol ethers with Grignard reagents.

REACTIONS OF CYCLIC OXIDES UNDER BIFUNCTIONAL HETEROGENEOUS ACID-BASE CATALYSIS
Cifra: ХимияThe reactions of cyclic epoxides form the basis for many industrial chemical technology processes. Unlike simple ethers, oxiranes tend to undergo nucleophilic cleavage reactions. The chemical properties of cyclic alkanes are primarily determined by their

Cyclic and Macrocyclic Organic Compounds - a Personal Review in Honor of Professor Leopold Ružička [PDF]
Kemija u Industriji, 2009 Ružička opened the field of cyclic molecules such as cyclic terpenes and cyclic ketones with up to 17 ring atoms. This work until now was extended in many directions such as cyclic paraffins, crown ethers and cryptands and cyclic ester amides.
