The Mo-catalyzed hydrostannation of propargylic amines and amides gave rise to functionalized vinylstannanes in good yield. The α-stannylated products were formed preferentially, which are interesting synthetic building blocks. If halogenated aromatic amines were subjected to this protocol, the products obtained could be converted into indole and isoquinoline derivatives through intramolecular Stille
