Abstract:
Allyl sulfides are bioactive phytochemicals found in garlic, onion, and other members of the genus Allium. Here we showed that diallyl disulfide and diallyl trisulfide can transfer allyl side chains to low molecular weight thiols. Diallyl monosulfide is inert with respect to this allyl transfer reaction. On the other hand, diallyl sulfone, a known metabolite of diallyl monosulfide, alkylates both amines and thiols under physiologically relevant conditions via isomerization to an electrophilic vinyl sulfone.

Preparation of Alkynes: Alkylation Reaction
Alkylation of terminal alkynes with primary alkyl halides in the presence of a strong base like sodium amide is one of the common methods for the synthesis of longer carbon-chain alkynes. For example, treatment of 1-propyne with sodium amide followed by reaction with ethyl bromide yields 2-pentyne.
