Why doesn't this carry on to form a ring by deprotonating the alpha carbon and the negatively-charged carbon attacking the C=O?
6. A solution (0.0004 M) of Fe(S2CNEt2)3 (see the structural drawing below) in chloroform
has absorption bands at:
350 nm (absorbance A = 2.34);
514 nm(absorbance A = 0.0532);
Calculate the molar absorptivity values for these bands. Comment
on their possible nature (charge transfer transitions or d-d
S
N-
transitions?).
