Lead acetate dichlorofluorescein

Alcohols, polyols, sugars Lead(IV) acetate-dichlorofluorescein Cleavage of vicinal diols... [Pg.4838]

The reaction is based, on the one hand, on the oxidative cleavage of vicinal diols by lead(IV) acetate and, on the other hand, on the reaction of dichlorofluorescein with lead(IV) acetate to yield a nonfluorescent oxidation product. The dichlorofluorescein only maintains its fluorescence in the chromatogram zones where the lead(IV) acetate has been consumed by the glycol cleavage reaction [1],... [Pg.326]

Alcohols (diols, polyols, sugan) Lead(IV) acetate -dichloro fluorescein Diol cleavage of vicinal diols, e. g. sugars, sugar alcohols. The lead tetraacetate consumed is no longer available to decompose the fluorescent dichlorofluorescein. [3, 8]... [Pg.31]

Lead tetraacetate-2,7-dichlorofluorescein (A) lead tetraacetate (saturated solution) in glacial acetic acid (B) 2,7-dichlorofluorescein in water (1%, m/v, or lower, down to 0.2%, if background interferes with detection) A and B are mixed 1 1 (v/v), then toluene (19 1, v/v) is added Plate is dipped in reagent for 10s, then heated at 100°C for 3 min All carbohydrates with vicinal diol groups, oxidized by lead tetraacetate, are detected fluorimetric scanning (excitation 313nm, emission 366 nm) 50-100pmol... [Pg.445]
