As. Batsanov et al., One pot synthesis of a chiral N-phosphine substituted iminophosphorane: X-ray structure and in situ NMR study, J CHEM S P1, (24), 2000, pp. 4237-4239
An X-ray crystal structure reveals that the attempted deprotonation of cycl
opropyl(triphenyl)phosphonium bromide with sodium amide affords a chiral N-
phosphine substituted iminophosphorane via an unusual mechanism that has be
en investigated by multi-nuclear and variable temperature in situ NMR spect
roscopy.
