Synthesis of New Fluorine Derivatives via Mannich Reaction

Three New compounds N,N(substituted) amino,N(3(2-fluorenyl))propanone- 3.(Ia),(Ib),(Ic), have been prepared using Mannich reaction from 2- Acetyl fluorine with formaldehyde and secondary amine. For(diethanol amine, diethyl Amine, N- methyl. Nphenyl amine) in an acidic medium HCl which gave these compounds: )N, N bis (2- hydroxy ethyl) amino, N (3 (2-fluorenyl)) propanone-3 (Ia). )N, N bis (ethyl) amino, N (3 (2- fluorenyl)) prpanone-3 (Ib). N-methyl. N-phenyl amino, N (3 (2- fluorenyl)) propanone-3 (Ic). The structure of these compounds have been checked by spectrum analysis: (IR, 1HNMR, 13c-NMR, LC-MS).
