Abstract: A set of twelve new N,N'-diphenylalkanediamides was prepared by the reactions of acyl chlorides with appropriate anilines. The inhibition of oxygen evolution rate (OER) in spinach chloroplasts by the synthesized compounds was investigated. With the exception of N,N'-bis(3,4-dichlorophenyl)butanediamide (IC50 = 22 μmol dm-3), the other studied derivatives of N,N'-diphenylbutanediamide did not affect photosynthetic activity of spinach chloroplasts. The OER-inhibiting activity of N,N'-bis(3,4-dichlorophenyl)alkanediamides (alkane = butane, pentane, hexane, octane, nonane) showed a linear decrease with increasing lipophilicity of the studied compounds.
