Electrochemical oxidation-induced benzyl C–H carbonylation for the synthesis of aromatic α-diketones

Electrochemical oxidation-induced direct carbonylation of benzyl C–H bond for the synthesis of aromatic α-diketones is described. In this process, tetrabutylammonium iodide (nBu4NI) not only acts as an electrolyte, but its iodine anion is oxidized to an iodine radical at the anode, acting as a hydrogen atom transfer agent. The iodine radical extracts the benzyl hydrogen atom and causes the carbonylation of the benzyl position, where O2 in the air is used as an oxygen source.

Iron-Promoted Domino Dehydrogenative Annulation of Deoxybenzoins and Alkynes Leading to β-Aryl-α-Naphthols

A strategy for synthesis of β-aryl-α-naphthols has been established through an iron-promoted domino C(sp3)?H/C(sp)?H and C(sp2)?H/C(sp)?H dehydrogenative coupling of deoxybenzoins and alkynes. The synthesis uses inexpensive materials

An iodine/DMSO-catalyzed sequential one-pot approach to 2,4,5-trisubstituted-1H-imidazoles from α-methylene ketones

A sequential one-pot approach to 2,4,5-trisubstituted imidazoles has been developed from α-methylene ketones and aldehydes. This methodology employs air-moisture stable reaction conditions and an inexpensive iodine/DMSO system affording a diverse range of known and novel (substrate scope) 2,4,5-trisubstituted imidazoles in moderate to excellent yields. The iodine/DMSO system was extended to the domino convergent synthesis of two functionalized intermediates, benzil and benzaldehyde, to produce the final product.
