CH), 4.22 (10H, s, Fc-H), 4.54 (4H, m, Fc-H), 4.98 (4H, d, Fc-H), 7.55 (2H, s, Cp-H). 18.10 (1H,[link widoczny dla zalogowanych], s, OH) ppm. Results and discussion 1 HNMR analysis produced Ao H: 18.07 ~ 18.20ppm single peak and 7.16 ~ 7.72ppm single peak with the reported quality of hydroxyl and the cyclopentene ring in the proton chemical shift consistent. All compounds in the H: 4_10 (10H,[link widoczny dla zalogowanych], Hc),[link widoczny dla zalogowanych], 4,5 o (4H, Hb), 4.90 (4H, Ha) ppm peak-there are three groups, respectively, a single peak, multiple bee and the ■ weight peaks corresponding to three kinds of ferrocene protons: proton magnetic resonance peaks of other compounds are consistent with the presumed structure, all compounds have the structure shown in c. 2 IR analysis of the product are formed in the 3440cm hydrogen bonds near the OH stretching vibration absorption peak of the 1590 ~ 1630cm strong absorption peak is the formation of hydrogen bonds the carbonyl absorption of bees,[link widoczny dla zalogowanych], which the literature literature, 1006 ~ 1180cm differential IR absorption peaks of ferrocene 9 ~ 10 / ~ m ... rules compliance. 3 Description of the structure c c structure can be A, B resonance structure,[link widoczny dla zalogowanych], ie the product of fulvene 6 of the hydroxyl proton to quickly move between the two oxygen atoms. This is consistent with the literature, but also with the reported similarity of Organic Chemistry 995 ==
