Heterobimetallic Ir–Sn catalysis: aza-Friedel–Crafts reaction of N-sulfonyl aldimines
摘要:
The heterobimetallic complex [Ir(COD)(SnCl3)Cl(mu-Cl)](2) catalyzes the aza-Friedel Crafts reaction of 1,3,5-trimethoxybenzene, as well as substituted indoles with N-sulfonyl aldimines leading to the formation of diarylamines and triarylmethanes in good yields. The symmetrical triarylmethanes were also obtained from diarylamines and suitable nucleophiles via simultaneous cleavage of sp(3) C-N bond and elimination of 1,3,5-trimethoxybenzene.

The FeCl3 center dot 6H(2)O-catalyzed Friedel-Crafts arylation reactions of N-sulfonyl aldimines or sulfonamidesulfones with electron-rich arenes and heteroarenes, which lead to the formation of triarylmethanes and bis-heteroarylarylmethanes, are developed. The use of mild reaction conditions, low catalytic loading, high yield, and single step synthesis are the advantages of the present procedure.
RUTHENIUM PORPHYRIN CATALYZED FRIEDEL–CRAFTS TYPE REACTION OF ARENES WITH IMINES
Cationic ruthenium porphyrin complex was found to be an efficient catalyst for the Friedel-Crafts type reaction of arenes with imines. The use of a structurally rigid tetradentate porphyrin as the equatorial ligand and weakly coordinating axial ligand is the key to bring out the catalytic reactivity of ruthenium for the reaction.
