Mediated by a catalytic amount of FeCl3, the C–H alkylation of S,S‐functionalized internal olefins, i.e., α‐oxo ketene dithioacetals and their analogues, was efficiently achieved using simple ethers and toluene derivatives as the coupling partners, di‐tert‐butyl peroxide (DTBP) as the oxidant, and DABCO⋅6 H2O as the additive. The alkylthio functionality is essential for the internal olefinic C–H bond

Visible-light-induced direct C–H arylation of S,S-functionalized internal alkenes, that is, α-oxo ketene dithioacetals and analogues, has been efficiently realized with aryldiazonium salts (ArN2BF4) as coupling partners and Ru(bpy)3Cl2·6H2O as photosensitizer at ambient temperature. The strategy to activate the internal olefinic C–H bond by both the alkylthio and electron-withdrawing functional groups
The hypervalent iodine reagent PhI(OAc)2 (PIDA) mediated the formal oxidative C=Cbond cleavage and subsequent cyclization of internal olefins, that is, α‐oxo‐ketene N,N‐acetals, which afforded substituted oxazolines. Isothiazoline derivatives were obtained from the reactions of α‐thioxo‐ketene N,N‐acetals with PIDA under the same conditions. Hydrolysis of the resultant oxazoline derivatives led to
