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

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

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.

COMPOUND AND COMPOSITION CONTAINING THE SAME, AND METHOD FOR MANUFACTURING DEVICE USING THE COMPOSITION

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.
