FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to new individual compounds of oxazines class that elicit fluorescent properties and can be used as the parent substances for synthesis of new heterocyclic systems and as substances used for marking samples and additives for light-reflecting dyes. Invention describes 6-aryl-5-quinoxalinyl-2H-1,3-oxazine-4-ones of the general formula:
wherein (a) Ar means C6H5; R means C6H4Br-p; R' means C6H4OCH3-p; (b) Ar means C6H4CH3-p; R means C6H4OCH3-p; R' means C6H4Br-p eliciting fluorescent properties. Also, invention describes 6-aryl-5-quinoxalinyl-2H-1,3-oxazine-4-ones as agents used for marking, copying and recognizing with applying ultraviolet radiation, and 6-aryl-5-quinoxalinyl-2H,1,3-oxazine-4-ones as additives for light-reflecting dyes, and a method for preparing 6-aryl-5-quinoxalinyl-2H-1,3-oxazine-4-ones. Invention provides preparing new compounds eliciting useful properties.
EFFECT: improved preparing method, valuable properties of compounds.
