Introduction of Lipophilic Side Chains to N H-Sulfoximines by Palladium Catalysis Under Blue Light Irradiation.

Palladium catalysis under blue (LED) light irradiation allows conversion of N H-sulfoximines into products with long lipophilic side chains attached to the S═N moiety. The three-component reactions involve both radicals and organometallic intermediates stemming from alkyl bromides and butadienes. The substrate scope is broad, and the products are formed in moderate to good yields.
