Question

This compound or a cyclic relative is boiled when converting aromatic chlorides to fluorides in the Halex process. This is the simplest compound that can be activated by acetic anhydride in the Pummerer rearrangement. A “d6” derivative of this amphiphilic compound is often mixed with similar analogs of dichloromethane and chloroform to reduce its viscosity. This compound can be added to master mixes at 3 percent to inhibit secondary structures and decrease the (*) annealing temperature of GC-rich templates in PCR. (-5[1])The deuterated form of this compound shows a residual quintet peak at 2.50 ppm (10[1]-5[1])in proton NMR. This compound has a much higher boiling point than acetone, while only being different (10[1])at its central (10[1])atom. This polar (10[1])aprotic (10[1])solvent (-5[1])is rapidly (10[1])absorbed (10[1])by skin and leaves a taste of garlic. (10[2])For 10 points, name this organic solvent (10[1])that consists of two methyl groups and an oxygen double bonded to a central (10[1])sulfur atom. ■END■ (10[3]0[2])
