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
