The synthesis of TAS+ C3N3F4- (1) (TAS+ = (Me2N)3S+) and the reactions of 1 with Me3SiOSiMe3 and Me3SiCF3 to give TAS+ C3N3F2O- (2) and TAS+[(NCF)(NCCF3)(NC(CF3)(2)]- (4) are reported. An isomer of 4, TAS+[(NCCF3)2(NCFCF3)]-, compound 6, was obtained by fluoride ion addition to (CF3CN)3.

Copper-Catalyzed Tandem Reactions of 2-Amine-[1,3,5]triazines with Nitriles.
Journal of Organic Chemistry, 2019Copper-catalyzed intermolecular annulation of 2-amine-[1,3,5]triazines and aryl nitriles for the synthesis of [1,2,4]triazolo[1,5- a][1,3,5]triazines via N-C bond formation and oxidative N-N coupling [oxidative 3 + 2 cyclization] is presented.

Abstract Despite the widespread use of these chemicals, relatively little is known regarding their potential effects on the health of wildlife and humans. In light of such widespread use and limited information about health effects, there has been an in creasing interest in potential detrimental impacts due to unintended exposure ...
