Cuprous chloride was coordinated by diazabutadiene (DAB-R) ligands to form Cu(I)-(DAB-R) complexes, most of which have a 1:1 ratio of Cu to DAB-R as reported. In the case of a special DAB-iPP, N,N′-bis(2,6-diisopropylphenyl)-1,4-diaza-1,3-butadiene, an unexpected composition of complex was found with the formula Cu(I)Cl(DAB)2. When employed as catalyst for triarylamine synthesis from the coupling of aryl halides with primary and secondary arylamines, the new Cu(I)-(DAB-iPP) complex displayed high efficiency.
