note
-
Heating of a 1:1 inclusion compound (ß-CyD-2a) at 120 °C for 6h, followed by treatment with aq. DMSO and extraction with benzene gave pure E-(3-phenylallyl) methyl sulfide (E-3a) in 81 % yield. The S-acetylmethyl derivative smoothly extruded COS to give the corresponding sulfide in 90% yield. The methyl substituent on 2-position of the allylic moiety retarded the reaction rate.

Steric effect may be operative. Inspection of the optimized structures indicates that the OC - SCHRCH= bond of the secondary ones is elongated as compared with the primary ones.

note

The MO simulations on proton-coordinated reaction for 2A implied a different mechanism, i.e., [3,3]-sigmatropic rearrangement. The 6-31G* simulation predicts that fragmentation of COS does not occur and betaine-type intermediate is produced.
