1-Propanesulfonic acid, 1,1,2,3,3,3-hexafluoro- → 2,5-Diethoxy-4-p-tolylmercaptobenzenediazonium 1,1,2,3,3,3-hexafluoropropanesulfonate

Participants

Reaction Steps

50 g of 2,5-diethoxy-4-p-tolylmercaptobenzenediazonium chloride 1/2 ZnCl2 were dissolved in 1.5 1 of water. 20 ml of 1,1,2,3,3,3-hexafluoropropanesulfonic acid were then added dropwise to the filtered solution while stirring vigorously. The product, which precipitates as oily drops, solidified after a few minutes, was filtered off by suction, suspended in 1 1 of water while stirring vigorously, again filtered off by suction and, finally, dried. 56.5 g of 2,5-diethoxy-4-p-tolylmercaptobenzenediazonium 1,1,2,3,3,3-hexafluoropropanesulfonate were obtained as a fine, light brown powder.
