Pd-catalyzed domino Heck/borylation of acrylamides with B2pin2 is reported to generate synthetically useful indolinone-3-methyl boronic esters, via capturing σ-alkyl palladium with boron. Further functionalization of the obtained boronic ester qualify it as a new starting point for the functionalization of specific C(sp(3))-H bond. Moreover, the application of an Ugi-adduct as starting material or B2nep2 as an alternative boron source works equally well, making this a broadly applicable and robust method for the formation of a C-C and C-B bond in a single operation.
