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
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.
