Abstract

Postupak za dobijanje hlorbenzoksazola formule (I) (I) gde R1, R2i R4 uvek nezavisno jedan od drugog predstavljaju H, halogen, CN, NO2, C1-C5-alkil, C1-C5-alkoksi, aril ili ariloksi, pri čemu je svaki od poslednja četiri navedena ostatka supstitnisan-ili nesupstitl.lisan i (slučaj a) R3 je H, halogen, CN, N02, C1-C5-a1ki1, C1-C5-alkoksi, aril ili ariloksi, pri čemu je svaki od poslednja četiri navedena ostatka supstituisan ili nesupstituisan ili (slučaj b) R3 je hlor, naznačen time, što se benzoksazoli formule (II) (I) u kojima R1, R2i R4•imaju isto značenje kao u formuli (I) i R3 u slučaju (a) je definisan kao u formuli (I), odnosno R3 je u slučaju (b) vodonik, u prisustvu nekog kiselog katalizatora sa, sredstvom za hlorovanje prevodi u produkt monohlorovanja (I), odnosno u slučaju (b) sa viškom sredstva za hlorovanje u produkt dihlorovanja (I), gde R3 = hlor. Prijava sadrži još 9 zahteva.
