La. Hobson et al., ON THE ORIGIN OF 1,5-INDUCTION IN TIN(IV) HALIDE-PROMOTED REACTIONS OF 4-ALKOXYALK-2-ENYLSTANNANES WITH ALDEHYDES, Chemical communications, (8), 1998, pp. 899-900
A combination of experiment and theory has identified both the allylti
n trichlorides 3 (R-2 = Bn, H) as key intermediates in tin(rv) chlorid
e-promoted reactions of allylstannanes 1 (R-2 = Bn, H) and the transit
ion structures that are involved in their reactions with aldehydes.
