The invention relates to organic chemistry, in particular, it relates to substituted iron phthalocyanines (PcFe) and method of producing chlorinated aromatic hydrocarbons using these substituted PcFe as catalysts.

Chlorinated aromatic hydrocarbons belong to an important class of intermediates of organic synthesis, which can be obtained by the action of the common environmentally harmful gloriously agents, such as chlorine, hypochlorites, chlorine Sulfuryl. In the natural environment they are formed under the action of H2About2and Cl-in the presence of chloroperoxidase. Some of chlorinated aromatic hydrocarbons possess biological activity and therefore are of interest for the pharmaceutical industry.

Found, %: C 58,19; N 5,91; Cl 18,76. C11H9Cl. Calculated, %: C 57,92; N 5,94; Cl 19,0. Mass spectrum, m/z: 186 [M+], 171 [M-CH3]+, 143 [M-CH3-Och3+3]+, 93 [M-2CH3-Och3-Cl+3]+, 11 [M-CH3-ON3-Cl+3]+.

Example 18. Getting 2-chloro-phenol and 4-chlorophenol.

The reaction is carried out in aqueous solution as in example 5 using phenol, 0.1 ml of HCl solution (2.25 M) and 0.1 ml (2,2·10-3M) solution PcFe (II).

Get 2-chlorophenol and 4-chlorophenol in the ratio of 1:1,15, yield 90%.

Thus, pre the proposed substituted iron phthalocyanines are effective catalysts for the process of oxychlorination process of aromatic hydrocarbons, the way their application provides reception of chlorinated aromatic hydrocarbons with high speed (within 15-20 min; prototype - 6 h) in good yield and product quality.

1. Substituted iron phthalocyanines of General formula
