H2SO4 (catalytic) heat 2 + OH attack ortho to OH & para to X xanthene type dye: X = OH (fluorescein) X = N(CH2CH3)2 (rhodamine B) I What is the role of sulfuric acid in the above reaction? Explain mechanistically. (12 pts.)
Reaction A: Resorcinol + Phthalic Anhydride ---(H2SO4)---> Fluorescein (2) C6H6O2 + C8H4O3 ---(H2SO4)---> C20H12O5 Reaction B: 3-(dimethylamino)-phenol + Phthalic Anhydride ---(H2SO4)--> Rhodamine B (2) C8H11NO + C8H4O3 ---(H2SO4)---> C28H31ClN2O3 This reaction involves two subsequent Friedel-Crafts acylation reactions. What is the structure of the intermediate after the first Friedel-Crafts reaction?
please help! the final products woukd bw fluorescein for one and rhodamine for the other (2 different outcome but still the same method) B: 7) Mechanistically show how the following compound can be converted to the final product. (8 pts.) (Hint: It is related to one of your previous experiments this semester.) OH COOH X = OH or NET ators. They are often fluorescent and have been used corneal abrasions, as antibacterials and anticancer by a Friedel-Crafts acylation reaction. Friedel-Crafts...
