Sažetak
Starting from 1-chloro-butane-2-one (I) and 3-chloro-butane-
2-one (II), oximes Illa, b and IV as well as 2,4-dinitrophenyl
hydrazones Va, b and VI were prepared. 'H-nmr spectra show that
I gives a mixture of isomeric oximes Illa and IIIb (21 : 79) and
2,4-dinitrophenyl hydrazones Va and Vb (20 : 80). From ketone II
only anti isomers IV and VI were obtained. Signals were assigned
using ASIS method. From paramagnetic shifts obtained by LIS
method it was concluded that unshared pair of nitrogen electrons
participates in complex formation with rare earth atom.
