A silver halide photographic material containing at least one compound having a group which after being released from the compound by redox reaction becomes converted into a compound having the development restraining ability and which becomes further converted in the developing solution into a compound which has no substantial development restraining ability or which shows a marked decrease in such ability.

A variety of esters react with perfluoroalkyllithiums in situ generated from perfluoroalkyl iodides and methyllithium to give perfluoroalkyl ketones in good yields. Perfluoroalkyllithiums add to α, β-unsaturated esters only in the 1,2-addition mode even in the presence of copper salt. Exception was observed in the reaction with maleates where perfluoroalkylated succinic esters and normal 1,2-addition
