Abstract
One-pot synthesis of 6-bromo-4,4-dimethylthiochroman from bromobenzene is reported. The crucial connection between the three steps is that the byproducts in the first two steps are used as the catalyst in the third step. Compared with the previous route, this approach is of low consumption and low pollution.
