Hydrazides applied: A palladium‐catalyzed direct CH arylation of heteroarenes, with arylsulfonylhydrazides as the arylating reagents, has been developed (see scheme). The reaction is chemoselective, in that arylsulfonylhydrazides containing halogen substituents can be employed without participation of the halogen substituent in the reaction. The method offers a straightforward approach to a variety

coverage of emission wavelengths in the visible region (405–616 nm) with large Stokes shifts in C3‐Indo‐Fluor may be straightforwardly and succinctly achieved by the palladium‐catalyzed direct CHarylation of indolizines at the C3 position of the pyrrole ring (see figure). The fluorophores have successfully marked A375 cells.
