Abstract
In this paper, we described a palladium/norbornene-catalyzed ortho-C-H phosphormethylation of aryl iodides using XCH2P(O)RR', offering a reliable method for the modular synthesis of polysubstituted α-phosphorylated arenes. Alkenylation, hydrogenation, cyanation, methylation, and arylation were all viable termination steps compatible with the reaction. This method demonstrates excellent functional group tolerance and can be extended to the late-stage modification of bioactive molecules. Furthermore, the synthetic transformations of the products demonstrate the practical utility of this reaction.

Abstract
A new reaction mode of palladium/norbornene (Pd/NBE) cooperative catalysis is reported involving the selective coupling of two different carbon-based electrophiles for vicinal double C-H functionalization of five-membered heteroarenes in a site-selective and redox-neutral manner. The key is to use alkynyl bromides as the second electrophile, which allows vicinal difunctionalization of a wide range of heteroarenes including pyrroles, thiophenes and furans at their C4 and C5 positions. One- or two-step tetrafunctionalizations of simple pyrrole and thiophene have also been realized. The C2-substituted NBEs prove most effective in these reactions, and the mechanistic exploration discloses the origin of the high selectivity of this transformation. Synthetic utility of this method has been exemplified in the concise preparations of thiophene-containing organic materials and a protein kinase inhibitor analogue. Preliminary success has also been achieved in a direct annulation event, using a tethered ketone as the second electrophile.
