Desulfony lation

This Pd-catalyzed LiHBEts reduction is applicable to integrated chanical processes (ICPs), which allows integration of alkylation of allylic sulfones and reductive desulfony-lation under mild basic conditions in one pot to prepare various olefins. ... 

The DA reaction of frani-l-nitro-2-phenylsulfonylethy-lene (4a) [13] with 1,3-cyclohexadiene occurred smoothly at 60 °C to give nitro phenylsulfonyl bicyclo[2.2.2]octene 6a [14] (Table 15.1), which was then subject to desulfony-lation with DBU followed by the Barton-Zard reaction to...
