Palladium-catalyzed synthesis of triarylamines from aryl halides and diarylamines

Various triarylamines can be readily prepared in excellent yields by palladium-catalyzed cross-coupling reaction of aryl halides and diarylamines. The amination reaction takes place rapidly by using the catalyst combination of Pd(OAc)2 and a bulky and electron-rich ligands, P(t-Bu)3.

Organic amorphous material N,N,N,N′-tetraaryl(Ar12Ar2 2)-1,1′-biphenyl-4,4′-diamine

A series of N,N,N,N′-tetraaryl(Ar12Ar2 2)-1,1′-biphenyl-4,4′-diamine were synthesized by the Pd(0) catalyzed C-N bond formation methodology. The physical properties, including glass transition temperature (Tg), melting point (Mp) and oxidation potential were measured. For Ar1 = 2-naphthyl and Ar2 = 3-toly (4f) and Ar2 = 3-ethylphenyl(4h), the DSC charts indicate that they have Tg, but no observable Mp. These two compounds are amorphous in solid state. The X-ray powder diffraction pattern of 4f further confirmed that it is truly amorphous throughout the temperature range in which it is solid. Therefore, we have demonstrated that a low molecular weight organic solid can be amorphous. This is an important aspect in the preparation of morphologically stable amorphous thin film. Other compounds with Ar1 = Ph, 1-naphthyl while Ar2 = 3-toly or 3-ethylphenyl are normal compounds with both Tg and Mp when prepared in their glassy state by rapid cooling of their melt. The oxidation potentials for compounds with Ar1 = 1-naphthyl and 2-naphthyl and identical Ar2 are exactly the same. The molecular structural features must be important factors for an organic solid to be in the amorphous state.

Metal-Free Oxidative C-C Coupling of Arylamines Using a Quinone-Based Organic Oxidant

A variety of arylamines are shown to undergo oxidative C-C bond formation using quinone-based chloranil/H+ reagent as the recyclable organic (metal-free) oxidant system to afford benzidines/naphthidines. Arylamines (3°/2°) designed with various substituents were employed to understand the steric as well as electronic preferences of oxidative dimerization, and a mechanism involving amine radical cation has been proposed. The tetraphenylbenzidine derivative obtained via oxidative C-C coupling has been further converted to blue-emissive hole-transporting material via a simple chemical transformation. This study highlights the preparation of novel HTMs in a simple, economic, and efficient manner.
