“…Gas-liquid-solid and/or liquid-liquid-solid multiphase systems are commonly involved in chemical processes, such as hydrogenation [1][2][3][4], oxidation [5], and enzymatic reactions [6][7][8][9][10][11][12]. However, the overall performance of these processes is largely limited by the inefficient mass transfer step within the complex multiphase system, which is inherently attributed to the poor dispersion of one phase in another, and relatively small interfacial area [13][14][15].…”

“…More recently, the palladium-catalyzed oxidative carbonylation of simple ethylenediamine to imidazolidin-2-one (72% yield) (carried out in water at 100 °C with 1 mol% of palladium catalyst, under 40 atm of a CO/O2 mixture [83]) was reported [84]. More recently, the oxidative carbonylation of benzene-1,2-diamine to benzimidazolidin-2-one was accomplished in a biphasic water-toluene medium using Pd(OAc) 2 as palladium(II) source in the presence of BipyDS (disodium 2,2 -bipyridine-4,4 -disulfonate) as the water-soluble ligand [79]. The possibility of incorporating the 11 C radioisotope into a benzimidazolidin-2-one moiety using 11 CO, although in modest yield, has also been demonstrated [80].…”

Recent Advances in the Catalytic Synthesis of Imidazolidin-2-ones and Benzimidazolidin-2-ones

2-Imidazolidinone and its analogues are omnipresent structural motifs of pharmaceuticals, natural products, chiral auxiliaries, and intermediates in organic syntheses. Over the years, continuous efforts have been addressed to the development of sustainable and more efficient protocols for the synthesis of these heterocycles. This review gives a summary of the catalytic strategies to access imidazolidin-2-ones and benzimidazolidin-2-ones that have appeared in the literature from 2010 to 2018. Particularly important contributions beyond the timespan will be mentioned. The review is organized in four main chapters that identify the most common approaches to imidazolidin-2-one derivatives: (1) the direct incorporation of the carbonyl group into 1,2-diamines, (2) the diamination of olefins, (3) the intramolecular hydroamination of linear urea derivatives and (4) aziridine ring expansion. Methods not included in this classification will be addressed in the miscellaneous section.

“…In addition to the famous ligand of triphenylphosphine trisulfonate (TPPTS), ionic-liquid-modified phosphine ligands , and sulfonated salicylaldimine ligands have also been designed and synthesized for biphasic hydroformylation reactions. Sulfonated bipyridine palladium complexes were applied in the oxidative carbonylation reaction of amine under a biphasic condition of toluene/H 2 O . An ionic-tagged ferrocene–ruthenium catalyst was developed for the asymmetric hydrogenation of aromatic ketones in the biphasic toluene/H 2 O system .…”

Reusable N-Heterocyclic Carbene Complex Catalysts and Beyond: A Perspective on Recycling Strategies

et al. 2018

View full text Add to dashboard Cite

With the continuous development of N-heterocyclic carbene (NHC) chemistry during the past decade, NHC metal complexes have gained wide applications in the research field of organometallic catalysis. The recycling and reuse of NHC metal complexes, which have undergone continuous expansion and diversification, can enhance their catalytic performance, extend their range of application, and afford new routes to green chemistry. Taking NHC metal complex catalysts as the main topic, this review intends to present a comprehensive study of recycling strategies of organometallic catalysts. By an elaborative summarization and classification of recycling strategies, a clear picture of all available of recycling strategies for organometallic catalysts is presented and the advantages and disadvantages of various recycling strategies for specific reactions are discussed in detail. This review is written with the hope of serving as a modest spur to induce other scientists' further contributions in the fields of catalyst recycling and sustainable catalysis.
