An Fe-catalyzed conversion of aldehydes to ketones via [1,2]-shift has been developed. This skeletalrearrangement shows a wide substrate scope and chemoselectivity profile while exhibiting an excellent [1,2]-aryl or [1,2]-alkyl shift selectivity that is easily switched by electronic effects.

functionalization/acylation of strong aliphatic C(sp3)-H bonds is disclosed via an N-heterocyclic carbene (NHC)-catalyzed dehydrogenative coupling of aldehydes with simple alkanes. The inert aliphatic C−H bonds are efficiently cleaved through intermolecular hydrogen atom transfer, providing an alternative organocatalytic approach for alkane C−H functionalization under transition metal- and light free
