H. Maeta et al., UNEXPECTED OUTCOME OF NBCL5-PROMOTED SAKURAI REACTION - MECHANISTIC IMPLICATIONS RELEVANT TO C4H7+ SPECIES, Tetrahedron letters, 36(6), 1995, pp. 899-902
Use of NbCl5 in the Sakurai reaction gave an unexpected outcome. Allyl
silane reacted with aldehyde in 2:1-stoichiometry with concomitant for
mation of a cyclopropane ring. Mechanistic implications of this anomal
ous reaction related to C4H7+ species are discussed based on the exper
imental and theoretical (ab initio) studies.
