| titleOfInvention | Manufacture of 4-aryl-2-perfluoroalkyl-3oxazolin-5-one from aryglycine |
| abstract | A kind of process for the preparation of compound (I) represented by the formula below, where n denotes an integer of 1, 2, 3, 4, 5, 6, 7 or 8; and A is (formula) or (formula) L is hydrogen or halogen; M and Q independent of each other is hydrogen, halogen or CF3; R is hydrogen, halogen, NO2 or CHO; R1 and R2 independent of each other is hydrogen; and Z is O or S; the process includes the reaction of a compound having chemical formula II and compound having chemical formula III with at least 1g mw, where n is as described above, and X is OH or Cl, that undergoes in the presence of phosphorous trihalide of approx. 0.4-1.1g mw and a solvent or solvent mixture (selected from aryl hydrocarbon, nitrile, carboxyamide, hydrocarbon halide or their combination), at temperature 25-110 deg. C, and when X is OH, the process goes on in the presence of tri(C1-C4 alkyl) amine of at least 1g mw. |
