Application of Pd-catalysed amines arylation for the synthesis of benzopolyazamacrocycles
Amination of 1,2- or 1,3-dihalobenzenes by linear polyamines in the presence of Pd(dba)2/BINAP catalytic system can serve as a convenient one-pot procedure for the synthesis of benzopolyazamacrocycles.

Synthesis of polyaza macrocycles by palladium-catalyzed amination of 1,2-dibromobenzene and 2-bromo-1,3-dichlorobenzene
Palladium-catalyzed amination of 1,2-dibromobenzene with equimolar amounts of linear polyamines leads to the formation of polyaza macrocycles in low yields. The use of 2-bromo-1,3-dichlorobenzene as starting compound ensures considerably larger yields of
