Synthesis of diaryl ketones through oxidative cleavage of the C-C double bonds in N -Sulfonyl enamides

Kim, Hyunseok,Park, Sangjune,Baek, Yonghyeon,Um, Kyusik,Han, Gi Uk,Jeon, Da-Hye,Han, Sang Hoon,Lee, Phil Ho

, p. 3486 - 3496 (2018/04/14)

An oxidative cleavage of a C-C double bond is developed from the photochemical [2+2]-cycloaddition of diaryl N-tosyl enamides, aryl heteroaryl N-tosyl enamides, and N-tosyl cyclic enamides with singlet molecular oxygen, followed by a ring-opening reaction mediated by Cs2CO3 under air and sunlight without the use of photosesitizer, producing symmetrical and unsymmetrical diaryl, heterodiaryl, and cyclic ketones in good to excellent yields. Moreover, the oxidative cleavage of C-C triple bonds from 1-alkynes is demonstrated for the synthesis of symmetrical and unsymmetrical ketones from the Cu-catalyzed [3+2]-cycloaddition, Rh-catalyzed alkoxyarylation, photooxygenation, and ring-opening reaction in one-pot. Because the synthesis of the symmetrical and unsymmetrical diaryl and/or heterodiaryl ketones bearing an electron-donating group is not easy, the present method is notable.

A new efficient method for the preparation of intermediate aromatic ketones by Friedel–Crafts acylation

Jin, Xiaojun,Wang, Ailing,Cao, Hongyu,Zhang, Shujia,Wang, Lihao,Zheng, Xueliang,Zheng, Xuefang

, p. 5521 - 5530 (2018/04/30)

Abstract: As the most important method to prepare pharmaceutical and chemical intermediate aromatic ketones, Friedel–Crafts (F–C) acylation is used to seek a novel catalytic system which is imminently consistent with the concept of green chemistry. In this study, six deep eutectic solvents (DES) were synthesized for the Friedel–Crafts acylation reaction as a catalytic solvent. Among the six DES, choline chloride-zinc chloride ([ChCl][ZnCl2]2) proved to be the most competent candidate of electron-rich arenes with acylation reagent. It got the highest yield when 1.0 equivalent of [ChCl][ZnCl2]2 used with acyl halides at 70?°C. Recycled DES was reused directly without any extra process. After five cycles, the catalytic activity did not decrease significantly (80–85%). Finally, according to experimental validation, the possible mechanism of this reaction was considered.

P -Selective (sp2)-C-H functionalization for an acylation/alkylation reaction using organic photoredox catalysis

Pandey, Ganesh,Tiwari, Sandip Kumar,Singh, Bhawana,Vanka, Kumar,Jain, Shailja

supporting information, p. 12337 - 12340 (2017/11/20)

p-Selective (sp2)-C-H functionalization of electron rich arenes has been achieved for acylation and alkylation reactions, respectively, with acyl/alkylselenides by organic photoredox catalysis involving an interesting mechanistic pathway.

Direct C-H Cyanation of Arenes via Organic Photoredox Catalysis

McManus, Joshua B.,Nicewicz, David A.

, p. 2880 - 2883 (2017/03/11)

Methods for the direct C-H functionalization of aromatic compounds are in demand for a variety of applications, including the synthesis of agrochemicals, pharmaceuticals, and materials. Herein, we disclose the construction of aromatic nitriles via direct C-H functionalization using an acridinium photoredox catalyst and trimethylsilyl cyanide under an aerobic atmosphere. The reaction proceeds at room temperature under mild conditions and has proven to be compatible with a variety of electron-donating and -withdrawing groups, halogens, and nitrogen- and oxygen-containing heterocycles, as well as aromatic-containing pharmaceutical agents.

Paragraph 0152-0154, (2017/09/14)

PROBLEM TO BE SOLVED: To provide a compound which efficiently absorbs extreme ultraviolet radiation (EUV) such as KrF excimer laser and ArF excimer laser or an electron beam, has low sensitivity to OoB, and has high contrast. SOLUTION: A compound is represented by formula (1) and formula (2). In formulae (1) and (2), R1a and R1a are each independently a first monovalent organic group containing a divalent hydrocarbon group selected from an alkylene group; a group bonded directly to sulfur atom (S+) is the divalent hydrocarbon group; R2 is a hydrogen atom, an alkyl group and the like; R3 to R6 are a hydrogen atom, a hydroxy group or a second monovalent organic group; X- is a monovalent anion; and R1a and R1b in Formula (1) or R1a and R1b in Formula (2) may be bonded to each other to form a ring.
