We present a series of compounds by exploiting the unusual 1. 4-aryl shift observed for electron-rich 1. 3-dithiole-2-thione and tetrathiafulvalene (TTF) derivatives in the presence of perchloric acid. The mechanistic features of this rearrangement are discussed since this synthetic strategy provides an alternative route for the synthesis and functionalisation of sulfur rich compounds... https://www.freaknleather.com/product-category/cutting-lubricant/
