Kumar, Santosh published the artcileFriedel-Crafts-type Reaction of (Het)Arenes with Aldehydes/Ketones under Acid-Free Conditions using Neutral Ionic Liquid: A Convenient Routes to bis(Indolyl)methanes and Beyond, Recommanded Product: 1-Iodohexane, the publication is Asian Journal of Organic Chemistry (2022), 11(3), e202100749, database is CAplus.
Acid-free approach has been demonstrated for Friedel-Crafts-type reaction of (het)arenes with carbonyls using neutral ionic liquid (NIL). Methodol. is enabled to afford a densely functionalized bis(indolyl)methanes in good to excellent yields. This conditions is also compatible to the synthesis of 3,3-di(indol-3-yl)indolin-2-ones, bis(4-hydroxycoumarines) and triarylmethanes (total 40 examples; up to 98% yields). Gram-scale reactions and recycling study were carried out to demonstrate the practicality of present methodol. DFT studies illustrate the catalytic cycle involving simultaneous activation of C=O and indole C-H bond by NIL followed by C-C bond formation.
