ABSTRACT:

A five-membered cyclic thioether and a monoderivatized compound are formed after reaction between DMDS and a conjugated alkadiene. The simultaneous formation of these compounds allows the determination of the position of the double bonds.

Keywords: GC/MS, DMDS derivatives, conjugated alkadienes
