N2  - N,N-Dialkylaminosulfur trifluorides were first prepared in 1964 &#91;1&#93; and have since been developed as mild, easily handled fluorinating agents. &#91;2&#93; DAST, &#91;38078&#8211;09&#8211;0&#93;, the most widely used member of this family of reagents, is a pale yellow liquid that reacts violently with water. DAST is readily obtained from commercial sources (e.g. Aldrich or Lancaster) and can also be prepared by the reaction of N,N--di-ethylaminotrimethylsilane with sulfur tetrafluoride, followed by distillation of the crude product under reduced pressure. &#91;3&#93; DAST is known to be thermally unstable, undergoing either explosion or detonation when heated to &#62; 9&#176;&ordm;C. &#91;4&#93; The more thermally stable bis(2-methoxy-ethyl) aminosulfur trifluoride (Deoxo-Fluor&trade;, &#91;202289&#8211;38&#8211;1&#93;) has recently been made commercially available (Aldrich; Air Products and Chemicals) and is reported to have similar reactivity to DAST.&#91;5&#93;
