Thioacyl disulfides

Many dithiocarboxylate compounds of sulfur have been reported. Bis(thioacyl) disulfides 100, dimers of dithiocarboxylate ligands, are easily synthesized by oxidative dimerization of the corresponding dithiocarboxylic acids (Scheme 26) [151-154]. Their reactivities toward cycloaddition reactions and S-S bond cleavage have been investigated [155-157]. Bis(thioacyl) trisulfides 101 and tetrasulfides 102 are also prepared by treating the dithiocarboxylic acid with SCI2 and S2CI2, respectively [135]. [Pg.165]

Radical-induced decomposition of a bis (thioacyl) disulfide (e.g. Scheme 3).[i .i3-i61 is probably the most used method for the synthesis of RAFT agents requiring tertiary R groups. It is also possible to use this chemistry to generate a RAFT agent in situ during polymerization. ... [Pg.117]
