Abstract
Ph.D. (Chemistry)
Compounds 3-ferrocenylpyrazole (L1) 3-ferrocenyl-5-methylpyrazole (L2) and 4-
ferrocenyl-1-methyl diketone (L7) were synthesized according to literature procedure,
while compounds 3-ferrocenylpyrazolyl-methylenepyridine (L3), 3-ferrocenyl-5-
methylpyrazolyl-methylenepyridine (L4), 3-ferrocenylpyrazolyl-ethyl amine (L5) and 3-
ferrocenyl-5-methylpyrazolyl-ethylamine (L6) were prepared by phase transfer
alkylation of the 2,6-bis(bromomethyl)pyridine or 2-bromoethylamine with the
appropriate ferrocenylpyrazole L1 or L2 in a 1:1 ratio. These compounds L3-L6 show
structural isomers labelled a and b. The isomers were in a ratio of 4:1 for L3 and L4
while for L5 and L6 the isomers were 2:1 ratio...
