Improved synthesis of 2,3-dibromo-1-(phenylsulfonyl)-1-propene (DBP)

A convenient preparation of 2,3-dibromo-1-(phenylsulfonyl)-1-propene (DBP, 1) is available through the one-pot propargylation and oxidation of thiophenol to give the propargyl sulfone 11, which is isomerized and brominated in another one-pot reaction. The

Tunable Regioselectivity Associated with the Reaction of 2,3-Dihalo-1-(phenylsulfonyl)-1-propenes with Ambident Nucleophilic Reagents

2,3-Dihalo-1-(phenylsulfonyl)-1-propenes, obtained by the addition of bromine or iodine onto (phenylsulfonyl)propadiene, were found to exhibit interesting reactivity as both mono- and dielectrophiles, with the mode of reactivity depending upon the nature
