Photocatalytic intermolecular carboarylation of alkenes by selective C-O bond cleavage of diarylethers

Disclosed herein is a novel radical-mediated intermolecular carboarylation of alkenes by cleaving inert C-O bonds. The strategically designed arylbenzothiazolylether diazonium salts are harnessed as dual-function reagents. A vast array of alkenes are proven to be suitable substrates. The benzothiazolyl moiety in the products serves as the formyl precursor, and the OH residue provides the cross-coupling site for further product elaboration, indicating the robust transformability of the products.

Multifunctional Photoadditions of Stilbene to Derivatives of Caffeine and Benzothiazole

Electronically excited stilbene (1*) is trapped by 8-substituted caffeine derivatives (2a-f) or 2-chloro- (14) and 2-aminobenzothiazole (21) with variable results.While the electron-rich systems (2c,d) produce mostly propellanes, the halogeno compounds 2a,b and 14 react predominantly via insertion into the C-halogen bond.With 14 there occurs also some C-S insertion, with 21 only N-H insertion.Numerous succeeding reactions are elucidated and the reaction mechanisms discussed.Stilbene (1) photoadds hydrogen chloride to yield 16.

Known and New Types of Reactions in the Photoreaction of Stilbenes with Cyclic Imines

The photoreactions of stilbene and 1,4-diphenyl-1,3-butadiene with caffeine and of stilbene with benzothiazole, 1-methylimidazole and 2-(methylthio)benzothiazole have been investigated with respect to know (- , -cycloaddition , inserting -addition ), mechanistically new (uncatalyzed, substitutive -addition ) and principally new reaction types (substitutive -addition with substituent migration and cleavage of a double bond , substitutive -addition with cleavage of a double bond , intermolecular exchange of vinyl substituents ).The products are isolated and characterized analytically, spectroscopically (UV, 1H, 13C NMR) and by chemical transformations .The new reaction types are without precedence.They are formulated to occur via 1,4-diradicals.
