Mp. Lambert et al., DOUBLE STANNYLATION OF A PROPARGYL SULFID E USING TRIBUTYLTIN HYDRIDEIN THE PRESENCE OF THIOL, Journal of organometallic chemistry, 467(2), 1994, pp. 181-187
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 product
s. The application of a non-refocusing INEPT pulse sequence in Sn-119
NMR spectroscopy allows the determination of its stereochemistry by co
mparison of observed patterns with calculated spectra.
