Summary: The reactivities of o-carborane-fused silylenes towards molecules with CE (E = C, P) bonds were studied. Reactions of [(LSi:)C]2B10H10 (1a) with arylalkynes resulted in the formation of bis(silylium) carborane adducts 2 and 3. On the other hand, the reaction of 1a with a phosphaalkyne AdCP led to the synthesis of compound 4, featuring fused CPSi rings with a C=Si double bond and Si-Si single bond. Furthermore, the reaction of monosilylene 1b with AdCP yielded compound 5, containing a 1,2,3-triphosphetene core. The structures of the products were characterized by NMR spectroscopy and/or X-ray crystallography.

Summary: 4-Aryl-5-allyl-N-fluoroalkyl-1,2,3-triazoles were synthesized through a three-component reaction of fluoroalkyl azides, copper acetylides, and allyl halides. These compounds underwent aluminum halide-mediated transformation to N-(4-halo-2-aryl-cyclopentenyl) imidoyl halides by cyclization of vinyl cation intermediates, followed by halide capture. The cyclic products could be further utilized for the synthesis of N-alkenyl amides, amidines, isoquinolines, and tetrazoles, or for the subsequent modification of the cyclopentene ring.

Summary: This study presents the tandem intramolecular hydroarylation of alkynes accompanied by a 1,2-aryl shift. By utilizing the unique electron-rich character of the 1,4-dihydropyrrolo[3,2-b]pyrrole scaffold, pi-expanded, centrosymmetric pyrrolo[3,2-b]pyrroles were synthesized by reacting alkynes at the already occupied positions 2 and 5. The reaction only proceeds in the presence of cationic gold catalyst and produces unknown compounds with six conjugated rings. These synthesized compounds have potential applications in the creation of new materials with various functionalities.

Summary: In this study, an efficient metal-free chemodivergent protocol for the synthesis of 1-substituted 9H-pyrrolo[1,2-a]indole derivatives was reported. By fine-tuning the catalyst and solvent system, trifluoromethyl, trifluoroethylcarboxylate, or carboxylic acid substituents can be introduced on the C1-position of these derivatives. The solvent and catalyst interaction were found to be crucial for the catalytic C-F activation in these transformations.

Summary: A rhodium-catalyzed formal [4 + 1]-cyclization reaction of aryl substituted pyrazoles with cyclopropanols via C-H bond activation/cyclization processes to selectively construct a series of carbonyl functionalized pyrazolo[5,1-a]isoindoles is reported. The reaction shows good functional group compatibility and a broad substrate scope with up to 84% yields. Mechanistic studies suggest that the C-H cleavage may be the rate-determining step in this transformation.

Summary: The first asymmetric (3+3)-cycloaddition of ortho-substituted phenyl nitrones with aryl cyclopropane carbaldehydes has been achieved using secondary amine catalysts. While other ortho-substituents gave 1,2-oxazinanes, ortho-hydroxy compounds provided a novel class of tetrahydrochromeno-1,2-oxazine cores through rare 1,3-aryl migration followed by cyclization. An unusual type of asymmetric approach was also discovered.

Summary: We have developed an iridium(III)-catalyzed C-H alkynylation reaction of 2-acylimidazoles with alkynyl bromides, which efficiently constructs both C(sp)-C(sp(2)) and C(sp)-C(sp(3)) bonds. The mechanism of this reaction was extensively studied using density functional theory (DFT) calculations. The calculated catalytic cycle starts with C-H activation, followed by a strain-controlled selectivity migratory insertion of an alkynyl bromide into the formed iridacycle. The resulting alpha-bromovinyl iridium species undergoes a rapid conversion into a more stable iridium vinylidene intermediate through a 1,2-bromine migration, and the adjacent silyl group migrates to give the C-H alkynylated product. The unique reactivity difference with respect to the substituent on the alkynyl bromide occurs during the 1,2-migration step, where a silyl group can highly stabilize the transition state through the beta-silicon effect.

Summary: Zwitterionic triarylmethylium dyes 1 and 2 with varied molecular assembly and charge transfer transition were synthesized using a tetraarylborate unit. These dyes exhibited solvatochromism and mechanochromism, allowing the color of the solid state to change upon dissolution & evaporation or grinding. Different crystal forms obtained from different recrystallization conditions independently reproduced the three colors, which were correlated with solid-state structures as demonstrated by diffuse reflectance measurement and powder X-ray diffraction. The unique color change of these dyes is suggested to originate from alterations in intermolecular interactions.

Summary: Tricyclic 1,4-dihydro-1,4-phosphasilines 3a,b were synthesized from Si(NR2)(2)-bridged imidazole-2-thione compounds 2a,b. Based on the calculated Frontier Molecular Orbitals (FMOs) of 3b, a possible P-selective P-N bond cleavage reduction could be predicted, and a redox cycle was established using solutions of P-centred anionic derivative K[4b]. The cycle started with the oxidation of K[4b] to form the P-P coupled product 5b, which could be chemically reduced by KC8 to regenerate K[4b].

The analysis indicates that the 1,2-disilabenzene and 1,2-digermabenzene have lower aromaticity compared to benzene due to the presence of incompletely delocalized pi electrons on their cyclic conjugation systems.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
