Refractometric studies of molecular complexes ofDDT with some compounds of biological interest

摘要: Formation of molecular complexes betweenDDT as acceptor and indole, 2-methylindole, 3-methylindole, benzene naphthalene donors have been studied in carbon tetrachloride using refractometric differential measurements. Titration techniques through these measurements indicated1∶1 stoichiometry complexes. Equilibrium constants (K1) extent electronic polarization were calculated. Two types observed, one association involving primarily the benzhydryltrichloromethyl grouping ofDDT with a polar complexing agents, other interaction theDDT aromatic π-electron system π-electrons molecule. These data support charge-transfer complex formation hypothesis for mode action on level.
