- Abstract
Condensation of acetylferrocene with 5-phenyl(4-methylphenyl)-1,2-oxazole-3-carbaldehydes afforded ( Е)-3-[5-phenyl(4-methylphenyl)-1,2-oxazol-3-yl]-1-ferrocenylprop-2-en-1-ones. Reactions of ( Е)-3-[5-(4-methylphenyl)-1,2-oxazol-3-yl]-1-ferrocenylprop-2-en-1-one with semicarbazide, thiosemicarbazide, and hydroxylamine led to the formation of 5-[5-(4-methylphenyl)-1,2-oxazol-3-yl]-3-ferrocenyl-4,5-dihydro-1 H-pyrazole- 1-carboxamide, 5-[5-(4-methylphenyl)-1,2-oxazol-3-yl]-3-ferrocenyl-4,5-dihydro-1 H-pyrazole-1-carbothioamide, and 5-(4-methylphenyl)-3'-ferrocenyl-4',5'-dihydro-3,5'-bi-1,2-oxazole respectively. Reactions of ( Е)-3-[5-(4-methylphenyl)-1,2-oxazol-3-yl]-1-ferrocenylprop-2-en-1-one with guanidine and thiourea result in 4-[5-(4-methyl-phenyl)-1,2-oxazol-3-yl]-6-ferrocenylpyrimidin-2-amine and -2-thione respectively.
