Bromonium salts, which are hypervalent bromine reagents, have been explored as being
strong electrophiles owing to their extremely high nucleofugalities. Only one example of their …

… The alkylation of 4f to furnish 9 proceeded, although the reaction rate was quite slow.
Additionally, the reaction of isolated 9 under standard conditions did not provide the corresponding …

… monocationic XB donor 8, the charge is on the pyridinium motif and thus the halogen-bond-donating
moieties are neutral, the inactivity of the analogous noncationic XB donor 9 clearly …

A simple and general method for anti-selective hydrosulfonylation of unactivated alkynes
with sulfonyl chlorides in the presence of a catalytic amount of phenanthroline-based Lewis …

Herein, we present the synthesis of chiral triazole-based diaryliodonium salts and their
application as monodentate asymmetric iodine(III) derivates in halogen bond (XB) catalyzed …

… Therefore, our approaches to a stronger XBD than 3a for catalysis by introducing an iodine
atom or more electron-withdrawing group failed. Since the amidation of esters in 1b through …

Gold catalysis has, over the past decades, provided innovative organic transformations under
mild conditions with high chemoselectivities. It receives steadily growing attention thanks …
