Regioselective photostimulated homolytic tert-butylations for heteroaromatics such as pyridines or thiophenes are investigated with tert-butylmercury(II) chloride in the presence of toluene-p-sulfonic acid (PTSA) or 1,4-diazabicyclo[2.2.2]octane (DABCO) respectively. While the promotion effect of acid is quite strong for basic pyridines, the acid does not promote the reaction effectively for non-basic
