The Horner–Wittig reaction of (1a,b) with phenyl isocyanate or dehydration of amides (4c–g) gave the C-sulphenylketenimines (3a–g) in moderate yields. Thermolysis of (3b) gave 2-ethoxy-3-phenylthioquinolin-4-ol (7)via intramolecular cyclization, and the reactions of (3e) and (3f) with CN-diphenylnitrone gave 3-methylthioindolones (10a) and (10b), respectively.

We report the reactivity of new Cβ silylated ketenimines (4, 5, 6) and lithiated-silylated ketenimine 3 leasily generated from lithiated S-methyl-N-phenyl-trimethylsilylethanimidothioate 2] toward electrophilicreagents. Reactions of these ketenimines with strong electrophilicreagents such as sulfanyl chloride (PhSCl) gave access to new sulfanylated ketenimines. With less reactive species [benzenesulfinyl
