E. Fouquet et al., HALOGEN EXCHANGE IN SUBSTITUTED ALLYLTIN HALIDES STUDIED BY 2D NMR EXSY AS A TOOL TO ASSESS REACTIVITY, Journal of organometallic chemistry, 524(1-2), 1996, pp. 103-106
The halogen exchange between two monoallyltin compounds has been inves
tigated by Sn-119 2D NMR EXSY. It is demonstrated that the slower halo
gen exchange observed in the allylbisN,N(bistrimethylsilyl)aminotin ha
lide compared with the allyltin trihalides can be correlated with the
dramatic change in reactivity of these compounds in allyl radical tran
sfer.
