The 'H chemical shifts of the active bridge protons and their temperature dependences were measured in various solvents for a number of ortho-Mannich bases containing proton-donor (OH) and proton-acceptor (N) centres of varying strength. It was found that a maximum on the plot of 6 , versus ApK, occ

The interaction of p-nitrophenol with several electron-donors has been studied in aprotic and protic solvents by electronic absorption spectroscopy. The equilibrium data for different kinds of equilibria in 1,2-dichloroethane, n-butanol and acetonitrile have been obtained and discussed. The strong h

Using low-temperature UV, 1 H and 15 N NMR spectroscopy, we studied the easily polarizable bond of the labeled Mannich base[ 15 N] 2-(N,Ndiethylaminomethyl)-3,4,6-trichlorophenol (Cl 3 MB) dissolved in dichloromethane and in a 2 : 1 mixture of CDF 3 and CDClF 2 . Whereas at high temperature the mol
