<br/>1,3,5-Triaryllbenzene core is shown to be an important synthetic motif in the development of organic light emitting diodes (OLEDs), synthesis of dendrimers and fullerene fragments. Direct synthesis of 1,3,5-triarylbenzenes by self-condensation from the corresponding acetophenone derivatives was achieved earlier in our laboratories using Nafion-H as reusable catalyst. Howerver large amount (30 wt%) of the catalyst and higher temperatures are required for the reactions. Now, we are able to obtain the products using sustainable metal triflate catalysts such as Ga(OTf)<sub>3</sub> in much lower amounts (2 mol% ) and lower tempartures. The reaction occurs in tolune as solvent and under neat conditions. The products can be separated by simple crystallization in most cases. Details of the reactions and the conditions will be presented.
