Diallyl disulfide and the related trisulfide are produced by decomposition of allicin, which is released upon breaking the cells of the Alliaceae plants, especially garlic. The diallyl disulfide yield is the highest for the steam distillation of garlic bulbs which contain about 2 wt.% of diallyl disulfide-rich oil. Diallyl disulfide can also be ...

Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3] Allicin is an antifeedant, i.e. the defense mechanism against attacks by pests on the garlic plant. [4] Allicin is an oily, slightly yellow liquid that gives garlic its distinctive odor. It is a thioester of sulfenic acid.
A disulfide ensemble is a grouping of all disulfide species with the same number of disulfide bonds, and is usually denoted as the 1S ensemble, the 2S ensemble, etc. for disulfide species having one, two, etc. disulfide bonds. Thus, the (26–84) disulfide species belongs to the 1S ensemble, whereas the (26–84, 58–110) species belongs to ...
Diallyl trisulfide (DATS), also known as Allitridin, is an organosulfur compound with the formula S(SCH 2 CH=CH 2) 2. It is one of several compounds produced by hydrolysis of allicin , including diallyl disulfide and diallyl tetrasulfide; DATS is one of the most potent.
Methyl methanethiosulfinate can also disproportionate to a 1:1 mixture of dimethyl disulfide and methyl methanethiosulfonate (CH 3 SO 2 SCH 3) and rearrange via a Pummerer rearrangement to CH 3 S(O)CH 2 SSCH 3. [20] [21] An unusual three-membered ring thiosulfinate (a dithiirane 1-oxide) has been prepared through rearrangement of a 1,3 ...
