Ketene dithioacetals in Organic Synthesis

Abstract Ketene dithioacetals were widely used in organic reactions. Herein, recent advances were summarized as five categories according to their triggered mechanisms: (1) nucleophilic enethiols; (2) formation of C-Pd-SR intermediates; (3) C-S bond cleavage; (4) substitution of SR; (5) reactions of the double bond. Reactions with alkanes, alkenes, alkynes, aldehydes, isocyanides, indonium ylides et al were discussed. We hope this review will promote future research in this area.
