Procedure

A solution of 12.2 grams (0.068 mole) of 5-methyl(2,2'-bithienyl) in 50 mL of heptane was stirred, and, in alternate portions, 17.8 (0.070 mole) of iodine and 12.4 grams (0.057 mole) of mercury (II) oxide were added. Upon completion of addition the reaction mixture stirred for 20 hours, and then was filtered through diatomaceous earth. The filtrate was concentrated under reduced pressure to a residual solid. The solid was recrystallized from ethanol to yield 5.2 grams of 5-iodo-5'-methyl(2,2'-bithienyl).
