Iodine-catalyzed Friedel–Crafts alkylation of electron-rich arenes with aldehydes: efficient synthesis of triarylmethanes and diarylalkanes

Amidation of Alcohols with Nitriles under Solvent-free Conditions Using Molecular Iodine as a Catalyst

“…In the present study, iodine was investigated as a catalyst for the reaction of alcohols with nitriles. Recently, iodine has been investigated as a potential efficient catalyst in several organic reactions because it has low toxicity [6][7][8][9][10][11][12][13][14][15][16][17][18] . In this study, we also investigated solvent-free conditions, from the viewpoint of green chemistry .…”

Novel Aryl-Imidazolium Ionic Liquids with Dual Brønsted/Lewis Acidity as Both Solvents and Catalysts for Friedel–Crafts Alkylation

“…TRAMs and DIAAs are also used as photochromic agents, dyes, and building blocks for dendrimers. More interestingly, ring-hydroxylated TRAMs have been also reported to exhibit significant antioxidant, antitumor, antitubercular, and anti-inflammatory activities [1][2][3].…”

Amberlyst‐15 as a Green and Efficient Reusable Catalyst for Friedel‐Crafts Alkylation of Activated Arenes with N‐Sulfonyl Aldimines and Synthesis of Bis‐triarylmethanes

“…The Friedel À Crafts reaction is one of the most commonly employed methods for the synthesis of bis-triarylmethanes, which involves the reaction of diarylmethanol or α-amido sulfones or N-sulfonyl aldimines or aldehydeds with activated arenes in the presence of an acid catalyst or Lewis acid. [36][37][38][39][40] Recently, transition metal-catalysed routes have emerged as an alternative methods to address these issues and provide structurally diverse triarylmethanes. Most of these reported methods utilized two steps and usage of more expensive and moisture sensitive catalysts are the major disadvantages.…”
