Abstract: the discovery, now all of a sudden, after the search term to 2-halo-4.6-bisaryl-1, 3, 5-triazine can bring unprecedented Bakhtyaryt conditions, effectiveness low and high Wbantajyt by TFA On the cyanuric halide with aromatics in the existence of at least one of Lewis acids. Lewis acid and at least one interaction.And here also Karwmatyat interaction unprecedented public aromatics Mntwt can be used to produce a room for 4, 6-2-halobisaryl-1.3.5-triazines. The Altjrbtaljdydt using dope's interaction with a Lewis acid Lewis acid, at least under certain reaction conditions, activate the vehicle configuration. 2halo-4.6-bisaryl-1.3.5 of cyanuric halide.In a preferred Ytmathad Lewis acids Lewis acid Wmnshtat interact to form a complex compound. The 2-halo-4, 6-bisaryl-l, 3, 5-triazines for industrial vehicles is the key intermediate of type - 2 2-oxyaryl) - 4, 3, 5-triazine 6-bisaryl-1 the stroke) of ultraviolet rays Bnfshyt absorbers UV. 32
