An efficient iridium-catalyzed dehydrogenation, ring-closure reaction, has been developed via a cascade sequence, in which [Cp?IrI2]2/Xantphos proved to be the most efficient catalyst for the synthesis of 2,4,6-triaryl-1,3,5-triazines from stable aryl-substituted alcohols and amidines. It was the first case of iridium catalyst successful application in such transformation.

Various 2,4,6-trisubstituted 1,3,5-triazines were smoothly formed via TBHP-mediated direct oxidative coupling of amidine and methylarenes. This tandem oxidation-imination-cyclization transformation exhibits a straightforward protocol to prepare 1,3,5-triazines from easily available starting materials and green oxidants under metal-free conditions.

A novel, straightforward method for the synthesis of 2,4,6-triaryl-1,3,5-triazines via copper-catalyzed cyclization of N-benzylbenzamidines in DMSO has been developed. Compared to other methods, the present protocol has a number of advantages such as - cost-effectiveness, avoidance of aldehydes or alcohols as reaction partners, and easy accessibility of starting materials, making it a highly practical approach to access various 2,4,6-triaryl-1,3,5-triazines.

By using [RuCl2(p-Cymene)]2/Cs2CO 3 as an efficient catalyst system, the readily available, inexpensive aryl methanols were firstly employed for dehydrogenative synthesis of aryl substituted 1,3,5-triazine derivatives. Due to the inherent stability of alcohols in contrast with aldehydes, our synthetic protocol is adaptable to a broad substrate scope, there is no need for stringent protection during the whole operation process, and it has the potential to prepare valuable products that are currently inaccessible or challenging to prepare using conventional methods. It is a significantly important complement to the conventional synthetic methodologies. This journal is the Partner Organisations 2014.
