Abstract
Herein, we report a general method for copper-catalyzed N-arylation of isatoic anhydrides with unsymmetrical iodonium salts at room temperature. The developed catalytic protocol is mild and operationally simple, and aryl(TMP)iodonium trifluoroacetate is employed as the arylating partner. The methodology offers the broad applicability of both structurally and electronically diverse aryl groups from aryl(TMP)iodonium salts to access N-arylated isatoic anhydrides in moderate to excellent yields (53-92%). Moreover, the substituted isatoic anhydrides are equally compatible with the protocol too. To demonstrate the synthetic utilities of the N-arylation process, we also report an alternative approach for biologically relevant fenamic acid derivatives and N,N'-diarylindazol-3-ones in a one-pot step economical system. In addition, the scale-up synthesis of flufenamic acid is also illustrated.

Abstract
Phosphatidylcholine-specific phospholipase C (PC-PLC) is a key enzyme involved in the metabolism of the mammalian phospholipid phosphatidylcholine into secondary messengers diacylglycerol (DAG) and phosphocholine. DAG and phosphocholine have been identified to amplify various cellular processes involved in oncogenesis such as proliferation, cell-cycle activation, differentiation and motility, therefore making PC-PLC a potential target for novel anti-cancer treatments. The current literature standard for PC-PLC inhibition, tricyclodecan-9-yl-potassium xanthate (D609), has been shown to arrest proliferation in multiple cancer cell lines, however, it is not drug-like resulting in low aqueous stability, making it a poor drug candidate. 2-Morpholinobenzoic acids have been shown to have improved PC-PLC inhibitory activity compared to D609, with molecular modelling identifying chelation of the carboxylic acid to catalytic Zn2+ ions in the PC-PLC active site being a key interaction. In this study, the carboxylic acid motif was replaced with a hydroxamic acid to strengthen the Zn2+ interaction. It was found that the hydroxamic acid derivatives displayed PC-PLC inhibitory activity similar, or better, than D609. Furthermore, these novel inhibitors had potent anti-proliferative activity in MDA-MB-231 and HCT-116 cancer cell lines, far greater than D609 and previous 2-morpholinobenzoic acids.

Abstract
We describe a gold (I)-catalyzed tandem O-nucleophilic addition/[3,3]-rearrangement reaction of N-hydroxybenzo[1,2,3]-triazin-4(3H)-ones with alkynes enabled by a biphenyl-2-yl phosphine ligand featuring a pendant amide moiety (L1). A variety of 1-(2-oxo-2-arylethyl)benzo [d][1,2,3]triazin-4(1H)-one derivatives were synthesized in good to excellent yields. The present protocol gives a rare example of simultaneous formation of C-O and C-N bonds in the gold(I)-catalyzed [3,3]-sigmatropic rearrangements.

Abstract
1-Acyl triazenes can be prepared by acid-catalyzed hydration, gold/iodine-catalyzed oxidation, or oxyhalogenation of 1-alkynyl triazenes. Crystallographic analyses reveal a pronounced effect of the acyl group on the electronic structure of the triazene function. 1-Acyl triazenes display high thermal stability, and only moderate sensitivity toward hydrolysis. They are compatible with basic and oxidative conditions, allowing subsequent transformation. Under acidic conditions, 1-acyl triazenes act as acylation reagents.

Abstract
Aromatic rings are found in a wide variety of products, including pharmaceuticals, agrochemicals, and functional materials. Diaryliodonium salts are new reagents used to transfer aryl groups under both metal-free and metal-catalyzed reactions and thereby synthesize arene-containing compounds. This minireview focuses on recent studies in selective aryl transfer reactions from unsymmetrical diaryliodonium salts under metal-free conditions. Reactions reported from 2007 to 2017, which represents a period of significant growth in diaryliodonium salt chemistry, are presented and organized by the type of reactive intermediate formed in the reaction. Specifically, reactions involving λ3 -iodane, λ3 -iodane radical anions, aryl radicals, and arynes are discussed. Chemoselectivity trends in aryl transfer are compared and contrasted across reaction intermediates and translation to potential auxiliaries are posited.

Abstract
The mechanism of arylation of N-heterocycles with unsymmetric diaryliodonium salts is elucidated. The fast and efficient N-arylation reaction is interpreted in terms of the bifunctionality of the substrate: The consecutive actions of properly oriented Lewis base and Brønsted acid centers in sufficient proximity result in the fast and efficient N-arylation. The mechanistic picture points to a promising synthetic strategy where suitably positioned nucleophilic and acidic centers enable functionalization, and it is tested experimentally.

Abstract
Diaryliodonium salts have recently attracted significant attention as metal-free-arylation reagents in organic synthesis, and efficient access to these salts is critical for advancement of their use in reaction discovery and development. The trimethoxybenzene-derived auxiliary is a promising component of unsymmetrical variants, yet access remains limited. Here, a one-pot synthesis of aryl(2,4,6-trimethoxyphenyl)iodonium salts from aryl iodides, m-CPBA, p-toluenesulfonic acid, and trimethoxybenzene is described. Optimization of the reaction conditions for this one-pot synthesis was enabled by the method of multivariate analysis. The reaction is fast (<1 h), provides a high yield of product (>85% average), and has broad substrate scope (>25 examples) including elaborate aryl iodides. The utility of these reagents is demonstrated in moderate to high yielding arylation reactions with C-, N-, O-, and S-nucleophiles including the synthesis of a liquid crystal molecule.
