The quaternary salts of rigidized 1,3-oxazole compounds of the formula: ##STR1## where R is either H or CH.sub.3 O. The compounds are produced in a modif Robinson-Gabriel synthesis of oxazoles. These dyes are used in solution with non-interfering polar solvents, such as ethanol and H.sub.2 O, to form lasing media useful in dye lasers.
刚性化的1,3-
噁唑化合物的第四級盐的公式为:##STR1##其中R是H或CH.sub.3 O。这些化合物是通过改进的Robinson-Gabriel
噁唑合成法生产的。这些
染料与不干扰极性溶剂(例如
乙醇和H.sub.2 O)一起使用,形成用于
染料激光器的激光介质。
