| titleOfInvention | PROCESS FOR THE PREPARATION OF 2-POSSIBLE OXAZOLIUM SALTS |
| abstract | Such compounds are important as intermediates for the preparation of dyes which can be used as sensitizers for electrophotographic layers as well as for potentially biologically active substances. With the invention is to be achieved, the unsubstituted in the 2-position oxazolium salts of readily available starting materials in one step in higher yields and greater purities than before to synthesize. This is erfindungsmaessig in such a way that a-aminoketones with reactive formic acid derivatives to the unsubstituted in the 2-position oxazolium salts of type I, wherein R 1, R 2, R 3 is preferably a substituted or unsubstituted aryl or heteroaryl, R 2 is optionally H and Z is the anion of Represented mineral acid or the metal salt of mineral acid, are reacted. Formula I |
