TL;DR: The results show that RCGs were capable to host and catalyze various water-insoluble bromo/thiocyanato substrates in water without the use of any co-organic solvents.
Abstract: A family of three
spatially directional
resorcin[4]arene cavitand glycoconjugates (RCGs) have
been applied as efficient recoverable and reusable inverse phase transfer
catalysts for eco- and environmentally friendly thiocyanation and
2-amino-1,3-thiazole formation reactions in water. The results show
that RCGs (1 mol %) were capable of hosting and catalyzing
various water-insoluble bromo/thiocyanato substrates in water without
the use of any co-organic solvents. The recoverability and reusability
of RCG catalytic systems, that is, RCG1 and RCG3, were also examined upon a simple extraction of the desired
products using DCM or ethyl acetate, followed by subjecting the recovered
aqueous solution containing the RCG catalysts to the
next reaction cycles.

24 Mar 2020TL;DR: In this paper, compositions for non-aqueous lithium ion extraction and methods of nonaqueous lithium ion extraction are described. But they do not consider the use of octolig® or a methyl derivative thereof.
Abstract: Described herein are compositions for non-aqueous lithium ion extraction and methods of non-aqueous lithium ion extraction. In some embodiments, Octolig® or a methyl derivative thereof can be used to extract lithium and/or other ions from a non-aqueous substrate.
