A monoalkoxy phenyl group as a dummy ligand on indolyl(aryl)iodonium imides, which is related to the N-I bonding hypervalent iodine(III) compound, for the copper-catalyzed indole-selective C-N coupling reaction was designed to provide 3-bissulfonimido-ind

Efficient exploration of [DMAPTs]+Cl?for base free and chromatography free preparation of sulfonate esters from phenols and alcohols and sulfonamides from amines was achieved in excellent yields. Majority of the phenols irrespective of their substituents electronic nature underwent tosylation nearly at same reaction rate with an average yield of 95%. For amines, ring activating substituents favors rapid sulfonylation while the ring deactivating substituents relatively lowers the rate of tosylation. Furthermore the reagent was employed for Chemoselective sulfonylation as well as solvent free tosylation of phenols and amines.

An efficient method for the construction of two distinct C aryl-Caryl bonds through the Ni-catalyzed Suzuki-Miyaura cross-coupling of phenols with arylboronic acids has been developed. This reaction proceeds through the in situ tosylation of phenols by using N,N-ditosylaniline as the sulfonylating reagent, which is highly active, markedly stable, and easily prepared. The scope with respect to the coupling partners - phenols and boronic acids - is broad, and sensitive functional groups are tolerated. Phenols, especially those containing an unprotected amino group, which are generally problematic for coupling under conventional one-pot conditions, are also viable substrates in this transformation.
