释义	tosyl /ˈtəʊsʌɪl / /ˈtəʊsɪl/ noun [as modifier] Chemistry Of or denoting the toluene-4-sulphonyl radical —SO2C6H4CH3, used in organic synthesis: tosyl chloride... In all experiments superparamagnetic particles of 4.5-m diameter (Dynabeads, Dynal, Hamburg, Germany) exhibiting reactive tosyl groups on the surface were used as magnetic tweezers. The choice of TsSePh, rather than a tosyl halide, as the precursor of tosyl radical is based on the greater stability of the resulting selenides with respect to elimination compared to the halides. Origin 1930s: from German, from to(luol) and s(ulphon)yl.
