Rhodium-Catalyzed β-Acylalkylation of Allylbenzene Derivatives with Allyl Alcohols via C–C Bond Cleavage

The Journal of Organic Chemistry, 2023
We report here a deallylative β-acylalkylation reaction of allylbenzene derivatives with allyl alcohols in the presence of Cp*Rh catalysts. Allylbenzenes possessing pyridyl and pyrazolyl directing groups were converted to β-aryl ketones via the cleavage of C(aryl)-C(allyl) bonds.

Rhodium-diphosphite catalysed hydroformylation of allylbenzene and propenylbenzene derivatives

Inorganica Chimica Acta, 2006
The asymmetric hydroformylation of allylbenzenes and propenylbenzenes is an important tool for obtaining high value intermediates for the pharmaceutical and perfume industry. We have studied these reactions with rhodium-chiral diphosphite systems. The diphosphite ligands 6 and 7 with carbohydrate backbone have high regioselectivities in trans-anethole ...

Synthesis of Allylbenzene Derivatives through sp3 C–H Bond Functionalization of Toluene Derivatives

Synlett, 2017
An sp3 C–H bond-transformation reaction of toluene substrates to afford the corresponding allylbenzene derivatives is described. Optimum conditions were identified as involving the use of tetrabutylammonium iodide and tert-butyl hydroperoxide at 80 °C.

Regioselective Cp*Ir(III)-Catalyzed Allylic C–H Sulfamidation of Allylbenzene Derivatives

The Journal of Organic Chemistry, 2019
In this study we report the development of the regioselective Cp*Ir(III)-catalyzed allylic C-H sulfamidation of allylbenzene derivatives, using azides as the nitrogen source. The reaction putatively proceeds through a Cp*Ir(III)-π-allyl intermediate and demonstrates exclusive regioselectivity for the branched position of the π-allyl.
