Starazo triple switches - synthesis of unsymmetrical 1,3,5-tris(arylazo)benzenes
Heindl, Andreas H.,Wegner, Hermann A.
, p. 22 - 31 (2020)
Multistate switches allow to drastically increase the information storage capacity and complexity of smart materials. In this context, unsymmetrical 1,3,5-tris(arylazo)benzenes - 'starazos' - which merge three photoswitches on one benzene ring, were succe

Nickel/photoredox catalyzed C-N couplings of hydrazine-derived nucleophiles provide a powerful alternative to Pd-catalyzed methods. This continuous-flow photochemical protocol, optimized using design of experiments, achieves these couplings in short residence times, with high selectivity. A range of (hetero)aryl bromides and chlorides are compatible and understanding of process stability/reactor fouling has been discerned. This journal is
Synthesis of N-aryl hydrazides by copper-catalyzed coupling of hydrazides with aryl iodides.

[reaction--see text] A convenient method for intermolecular N-arylation of hydrazides with substituted aryl iodides in the presence of a copper catalyst and Cs(2)CO(3) is reported. The C-N coupling of N-Boc hydrazine with para- and meta-substituted aryl iodides afforded the N-arylated products A, regioselectively. A reversal in regioselectivity is observed for the arylation of benzoic hydrazide with ortho-substituted aryl iodides, providing the N'-arylated products B.
Regioselective synthesis of aryl hydrazides by palladium-catalyzed coupling of t-butylcarbazate with substituted aryl bromides
Wang, Zhongren,Skerlj, Renato T.,Bridger, Gary J.
, p. 3543 - 3546 (2007/10/03)
Substituted aryl bromides are coupled with t-butylcarbazate in the presence of a palladium catalyst and base to afford regioselectively, the corresponding amidation product or amination product depending upon the position of the substituents on the aryl b
