The synthesis of ethyl 4-oxo-1, 4-dihydro-1, 8-phenanthroline-3-carboxylate (2a) and some other 1, 8-phenanthrolines is reported. The ethylation of the above ester yields a thermochromic product 2b and some ethyl 4-ethoxy-1, 8-phenanthroline-3-carboxylate (3b). Reexamination of similar ethylations of analogous esters derived from 1, 7-phenanthroline and 1, 10-phenanthroline indicated formation of the
据报道,合成了4-氧代-1、4-二氢-1、8-菲咯啉-3-羧酸乙酯(2a)和其他一些1,8-菲咯啉的合成物。上述酯的乙基化产生热致变色产物2b和一些4-乙氧基-1、8-菲咯啉-3-羧酸乙酯(3b)。对由1,7-菲咯啉和1,10-菲咯啉衍生的类似酯的类似乙基化进行重新检查,表明形成了前者的O-乙基衍生物和后者的N-乙基衍生物。
