2O, in the absence of the phosphine, either in acidic media or in the presence of cyanide ion, required an overnight stirring (Ref. 8). Phenylsulfenylimines are much more resistant to conventional hydrolyses than the corresponding imines. See: Davis F.A., Slegeir W.A.R., Evans S., Schwartz A., Goff D.L., Palmer R. J. Org.

The E-Z isomerisation energy barriers of N-sulfenyl ketimines are, in general, relatively low (ca. 15-20 kcal/mol, coalescence temperatures around 50-70°C). See:

It would be interesting to investigate whether both pathways to (E)-6b from (E)-6a, summarised by means of arrows at the top of Scheme 3, are involved or not. In other words, if (Z)-6b is formed first and it immediately isomerises to (E)-6b, or if (E)-6b comes mainly from the small percentage of (Z)-6a that may be in equilibrium with (E)-6a under the reaction conditions. However, such a study is outside the scope of this communication
