Stable Abnormal N-Heterocyclic Carbenes and Their Applications Cite This: Chem
Chem Soc Rev REVIEW ARTICLE Stable abnormal N-heterocyclic carbenes and their applications Cite this: Chem. Soc. Rev., 2020, 49,1233 Samaresh Chandra Sau, a Pradip Kumar Hota,a Swadhin K. Mandal, *a Michele Soleilhavoupb and Guy Bertrand *b Although N-heterocyclic carbenes (NHCs) have been known as ligands for organometallic complexes since the 1960s, these carbenes did not attract considerable attention until Arduengo et al. reported the isolation of a metal-free imidazol-2-ylidene in 1991. In 2001 Crabtree et al. reported a few complexes featuring an NHC isomer, namely an imidazol-5-ylidene, also termed abnormal NHC (aNHCs). In 2009, it was shown that providing to protect the C-2 position of an imidazolium salt, the deprotonation occurred at the C-5 position, aﬀording imidazol-5-ylidenes that could be isolated. Over the last ten years, stable aNHCs have been used for designing a range of catalysts employing Pd(II), Cu(I), Ni(II), Fe(0), Zn(II), Ag(I), and Au(I/III)metalbased precursors. These catalysts were utilized for diﬀerent organic transformations such as the Suzuki–Miyaura cross-coupling reaction, C–H bond activation, dehydrogenative coupling, Huisgen 1,3-dipolar cycloaddition (click reaction), hydroheteroarylation, hydrosilylation reaction and migratory insertion of carbenes. Main-group metal complexes were also synthesized, including K(I), Al(III), Zn(II), Sn(II), Ge(II), and Si(II/IV). Among them, K(I), Al(III), and Zn(II) complexes were used for the polymerization of caprolactone and rac-lactide at room temperature. In addition, based on the superior nucleophilicity of aNHCs, relative to that of their nNHCs isomers, they were used for small molecules activation, such as carbon dioxide (CO2), nitrous oxide (N2O), tetrahydrofuran (THF), tetrahydrothiophene and 9-borabicyclo[3.3.1]nonane (9BBN).

Optical force is another interaction between light and matter, which was experimentally confirmed by Lebedev in late 19th century. Utilizing this force Ashkin proposed as “Optical Tweezers” in 1986 and demonstrated high potential in application to bio-science, which was awarded Nobel Prize Physics last year. Optical force was also expected to control molecular motion in solution and eventually chemical reaction. In 1988 we started to explore new molecular phenomena characteristic of optical force by combining optical trapping with fluorescence, absorption, electrochemical, and ablation methods. We have studied on microparticles, microdroplets, nanoparticles, polymers, supramolecules, micelles, amino acids and proteins in solution and reported their unique behavior. The remarkable achievement was performed in 2007 when the trapping laser was focused at solution surface. Various amino acids are crystalized, giving one single crystal at the position where trapping laser is focused and at the time when irradiated. This optical manipulation at solution surface is extended to dielectric and gold nanoparticles and to glass/solution interface. The initially trapped polystyrene nanoparticles at the focus form their periodical structure and scatter/propagate the trapping laser, shifting trapping site outside of the focus and forming a single large circle assembly.

Good conversions were observed at room temperature for the formation of di- and tri-substituted olefins by ring-closing metathesis. It also allowed for the ring-opening metathesis polymerization of cyclooctadiene, as well as for the cross-metathesis of cis-1,4-diacetoxy-2-butene with allyl-benzene, with enhanced Z/E kinetic selectivity over classical NHC-based catalysts.

Grotjahn,* and Guy Bertrand* Cite This: ACS Catal. 2020, 10, 5190−5201 Read Online ACCESS Metrics & More Article Recommendations *sı Supporting Information ABSTRACT: Through kinetic measurements, catalytic and stoichiometric experiments, and DFT calculations, we compare the catalytic activity of gold complexes supported by a variety of ligands (R3P, NHC, CAAC-5, CAAC-6, and BiCAAC) in the hydroamination and hydrohydrazination of alkynes. This study provides a rationale for the superior efficiency of a gold complex bearing a bicyclic (alkyl)(amino) carbene (BiCAAC). We demonstrate that this ligand motif, which is readily available, provides a durable gold catalyst that is able to compete with sophisticated state-of-the-art phosphine and NHC ligands, which feature secondary interaction capabilities.

Keith Hollis) A new bimetallic catalyst was synthesized from the metalation of 1,1'-(1,3-phenylene) bis(4-butyl-1 H-1,2,4-triazol-4-ium) iodide with silver oxide and the transmetalation of that complex with Rh(COD)2OTf. The structure of the compound, GJL-46, with 1 molecular formula C34H46I2N6Rh2, was confirmed with mass spectra analysis, H NMR and 13C NMR.
