2,3-dibromo-1,4-dimethylbenzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Follow the procedure of Example 6 except add 6 g of dibromo p-xylene and substitute 10.0 g of 2-chloro-4 ethoxycarbonyl phenol for 2-chloro-4-methoxyphenol to obtain 6.8 g of 1,1'-[1,4-phenylene bis(methyleneoxy)]-bis-[2-chloro-4-ethoxycarbonylbenzene].

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A series of ionene polymers were prepared according to the procedure of Example 1 except that equivalent amounts of iodo-propane, iodo-hexane, iodo-dodecane, iodo-butane or a mixture of dibromobutene and diiodopropane or diiodoethane were substituted for dibromo-p-xylene.
