4-(Tris(4-methyl-1H-pyrazol-1-yl)methyl)aniline
Bradley B. Garrison ; Joseph E. Duhamel ; Nehemiah Antoine ; Steven J. K. Symes ; Kyle A. Grice ; Colin D. McMillen , et al.
Abstract: 4-(tris(4-methyl-1H-pyrazol-1-yl)methyl)aniline was prepared in a 63% yield utilizing a C–F activation strategy from a mixture of 4-(trifluoromethyl)aniline, 4-methylpyrazole, and KOH in dimethylsulfoxide (DMSO). The identity of the product was confirmed by nuclear magnetic resonance spectroscopy, infrared spectroscopy, mass spectrometry, and single-crystal analysis. An analysis of crystals grown from the layering method (CH2Cl2/acetone/pentane) indicated two distinct polymorphs of the title compound. Moreover, density functional theory calculations utilizing the MN15L density functional and the def2-TZVP basis set indicated that 4-(tris(4-methyl-1H-pyrazol-1-yl)methyl)aniline forms with similar energetics to the previously reported unmethylated analog.

Photosensitized activation of diazonium derivatives for C-B bond formation
Ripak, Alexia ; De Kreijger, Simon ; Sampaio, Renato N. ; Vincent, Cooper A. ; Cauet, Emilie ; Jabin, Ivan , et al.
Abstract: Aryl diazonium salts are ubiquitous building blocks in chem., as they are useful radical precursors in organic synthesis as well as for the functionalization of solid materials. They can be reduced electrochem. or through a photo-induced electron transfer reaction. Here, we provide a detailed picture of the ground- and excited-state reactivity of a series of nine rare and earth-abundant photosensitizers with 13 aryl diazonium salts, which also included three macrocyclic calix[4]arene tetradiazonium salts. Nanosecond transient absorption spectroscopy confirmed the occurrence of excited-state electron transfer and was used to quantify cage-escape yields (i.e., the efficiency with which the formed radicals sep. and escape the solvent cage). Cage-escape yields were large; they increased when the driving force for photo-induced electron transfer increased and also tracked with the C-N+2 bond cleavage propensity, among others. A photo-induced borylation reaction was then investigated with all the photosensitizers and proceeded with yields between 9% and 74%.

Abstract: In this study, we developed a metal-free and highly chemoselective method for the reduction of aromatic nitro compounds. This reduction was performed using tetrahydroxydiboron [B2(OH)4] as the reductant and 4,4'-bipyridine as the organocatalyst and could be completed within 5 min at room temperature. Under optimal conditions, nitroarenes with sensitive functional groups, such as vinyl, ethynyl, carbonyl, and halogen, were converted into the corresponding anilines with excellent selectivity while avoiding the undesirable reduction of the sensitive functional groups.

After cooling, the reaction mixture was diluted with dichloromethane (10 mL), and the resulting mixture was filtered through a pad of Celite, which was washed three times with dichloromethane (30 mL). The filtrate was concentrated in vacuo. The crude product was purified by flash chromatography (silica gel; hexane/ethyl acetate, 10:1) to yield 8a (151 mg, 72%) |

---|---|---|
With pyridine; In dichloromethane; at 20℃;Cooling with ice; Inert atmosphere; | General procedure: To a stirred solution of amine derivative (3 .0 mmol ) in 10 mL of anhydrous py ridine under ice cooling, was addeda solution of 2 chlorosulfonyl benzoic acid 3.6 mmol ) in dichloroethane 10 mL) dropwise. The reaction mixturewas stirred at room temper ature under the nitrogen atmosphere for overnight. After completion of the reactio n(monitored by TLC), reaction mixture was diluted with chloroform (20 mL) and quenched with water (10 mL),extracted with chloroform (3x 3 0 mL), the organic layer was washed with 1N HCl (50 mL), then with water (50mL) The combined organic layers were dri ed over Na 2 SO 4 and evaporated in vacuo . The crude compoundrecrystallized from ethanol to afford the desired product 1a m |
