Method for the production of the linear alkylbenzenes based on Diels-Alder reaction of derivative of cyclopentadiene with straight chain alkyne or derivative thereof resulting in formation of tetrahaloalkylbenzene, which is simply dehalogenated in the micellar water solution by Zn reduction. Formula. where substituents R 1 and R' 1 are the same or different leaving groups selected from the group consisting of methyl, ethyl, and propyl, or R 1 and R' 1 together form ethylene glycol bridge; substituents R 2 , R 3 , R 4 , R 5 are the same or different selected from the group consisting of C1, Br, or I; R 6 is C 1 - C 16 alkyl chain or C 1 - C 16 haloalkyl chain; R 7 is substituent selected from the group consisting of H, C 1 -C 6 -alkyl; and R 6' is C 1 - C 16 straight alkyl chain. |
