IEDDA Reaction of the Molecular Iodine-Catalyzed Synthesis of 1,3,5-Triazines via Functionalization of the sp3 C-H Bond of Acetophenones with Amidines: An Experimental Investigation and DFT Study

The present work reports an inverse electron demand Diels-Alder (iEDDA)-type reaction to synthesize 1,3,5-trizines from acetophenones and amidines. The use of molecular iodine in a catalytic amount facilitates the functionalization of the sp3 C-H bond of acetophenones. This is a simple and efficient methodology for the synthesis of 1,3,5-triazines in good to excellent yields under transition-metal-free and peroxide-free conditions. The reaction is believed to take place via an in situ iodination-based oxidative elimination of formaldehyde. DFT calculations at the M062X/6-31+G(d,p) level were employed to investigate the reaction mechanism. Reaction barriers for the cycloaddition as well as a formaldehyde expulsion steps were computed, and a multistep mechanism starting with the nucleophilic attack by benzamidine on an in situ generated imine intermediate has been proposed. Both local and global reactivity descriptors were used to study the regioselectivity of the addition steps.

Blue thermally activated delayed fluorescent emitters having a bicarbazole donor moiety

Bis(4-(9′-phenyl-9H,9′H-[3,3′-bicarbazol]-9-yl)phenyl)methanone (BPBCz) and 9′,9′′′-((6-phenyl-1,3,5-triazine-2,4-diyl)bis(4,1-phenylene))bis(9-phenyl-9H,9′H-3,3′-bicarbazole) (TrzBCz) were investigated as thermally activated delayed fluorescent (TADF) emitters to exhibit blue emission color. A 3,3′-bicarbazole was a donor in the two TADF emitters, and benzophenone and triazine were acceptors of BPBCz and TrzBCz, respectively. Both BPBCz and TrzBCz behaved as high efficiency TADF emitters through a small singlet-triplet energy gap for the activation of delayed fluorescence. The BPBCz and TrzBCz TADF emitters offered high quantum efficiencies of 23.3% and 23.6% in the blue TADF devices.

A novel straightforward synthesis of 2,4,6-triaryl-1,3,5-triazines via copper-catalyzed cyclization of N-benzylbenzamidines

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.
