coupling component. The reactions were fast and quantitative. The granular PTFE, wastewater and excess HCl were then reused 11 times without deteriorating the reaction rate and product purity. Altogether, 22 industrial pigments and 3 azocompounds were synthesized and the reaction can produce up to 22.7 g of product in the laboratory. Somereactions require less than 2 equiv. of HCl and a mechanism explaining
