Abstract

1312031 2,3 - Dihydro - 1,3 - oxazinediones- (2,4) BAYER AG 12 Jan 1971 [5 Feb 1970 21 Nov 1970] 1447/71 Heading C2C Compounds of Formula I in which R 1 is alkyl, haloalkyl, cycloalkyl, norbornylalkyl, aralkyl, acyl or arylsulphonyl or aryl (which radicals may be substituted one or more times by alkyl, alkenyl, aryl, alkoxy, alkylmercapto, alkylsulphoxyl, alkylsulphonyl, haloalkyl, F, Cl, Br, I, CN, NO 2 , amino, alkylamino, dialkylamino or a heterocyclic radical); or R 1 is a heterocyclic radical; or R 1 is the group of formula R 2 is H and R 3 is Me, or R 2 and R 3 form a trimethylene radical which may be substituted one or more times by alkyl, and which compounds I are claimed per se provided that when R 2 is H and R 3 is Me, R 1 is neither phenyl nor benzyl, and when R 2 and R 3 form a trimethylene group, R 1 is neither phenyl nor α-naphthyl, are prepared by reacting, e.g. at 80-200‹ C. a 1,3- dioxinone of Formula III in which R 4 is H or alkyl and R 5 is alkyl or aryl, or R 4 and R 5 form a divalent alkylene group of formula -(CH 2 ) n - where n is 4, 5 or 6, with an isocyanate of formula R 1 -NCO in which R 1 has the meaning stated above except for the group of Formula II, or R 1 is a radical of Formula V
