Abstract

The 1H NMR spectra of benzocrown ethers I (R = H, halo, Et, Ac, NH2, etc.) and their mol. (charge transfer) complexes with picric acid were studied. The association constants of 12 kinds of these complexes were determine by the NMR method. On basis of the effect of substituents on the variation of the chem. shifts of various protons, the relation between the structure and the reactivity were discussed.

Key words: NMR SPECTROMETRY, CROWN ETHER COMPOUNDS, BENZENE P, STRUCTURE AND PROPERTY CORRELATION, CHEMICAL SHIFT, CHARGE TRANSFER COMPLEX, TRINITROPHENOL P, MOLECULAR COMPOUNDS, COMPLEX CONSTANT
