the aromatic carbons C9, C6, C16, C19, C7, C8, C17, C15, C18, C5, C14 and
C4 respectively.
4. Azomethine carbon (C11) gave peak at 152.69 δ ppm.
5. Two carbonyl carbons (C12 & C21) of indolinone ring became
deshielded due to the neighboring nitrogen atom and showed peak in
the down field at 161.59 and 162.30 δ ppm respectively.
6. C2 carbon of thiazole ring became most deshielded due to the
neighboring two nitrogen atoms and showed peak in the down field at
179.34 δ ppm.
3.6.4 ELEMENTAL ANALYSIS
Elemental analysis of the synthesized compounds was carried out on
Vario EL Carlo Erba 1108 which showed calculated and found percentage
values of Carbon, Hydrogen and Nitrogen in support of the structure of
synthesized compounds. The spectral and elemental analysis data are given
for individual compounds.
