In the presence of small amounts of p-thiocresol, hydrostannylation of propargyl p-tolyl sulfide promotes the unexpected formation of (Z)-1,2-bis(organostannyl)olefin instead of yielding normal addition products.The application of a non-refocusing INEPT pulse sequence in 119Sn NMR spectroscopy allows the determination of its stereochemistry by comparison of observed patterns with calculated spectra.Key words: Hydrostannylation; Nuclear magnetic resonance; INEPT; Propargyl sulfides
