highly atom‐economical tandem Pd/Au‐catalyzed route to α‐sulfenylated carbonylcompounds from terminal propargylic alcohols and thiols has been developed. This one‐step procedure has a wide substrate scope with respect to substituents at the α‐position of the alcohol. Both aromatic and aliphatic thiols generated the α‐sulfenylated carbonyl products in good to excellent yields. A mechanism is proposed in

Alkyl and aryl cyclopropylidenealkyl sulfides 2, 4 and 5 were converted to give access to 1-(arylthio)vinylcyclopropanes 3 by light induced or acid catalyzed 1,3-shift of the arylthio group. Some results on the reactivity of sulfides 2, 4 and 5 are reported.
