Syntheses of α-stannylated and α-iodinated enamides via molybdenum-catalyzed hydrostannation.

α-Stannylated and α-iodinated enamides can easily be obtained by molybdenum-catalyzed regio- and stereoselective hydrostannation and subsequent tin-iodine exchange. These functionalized enamides are interesting building blocks for a wide range of cross-coupling reactions giving access to various types of α-substituted enamides.
