Reactions of thioketones possessing a conjugated C=C bond with diazo compounds
Egli, Daniel H.,Linden, Anthony,Heimgartner, Heinz
, p. 3041 - 3055 (2008/01/27)
The reactions of several thioketones containing a conjugated C=C bond with diazo compounds were investigated. All of the selected compounds reacted via a 1,3-dipolar cycloaddition with the C=S group and subsequent N2 elimination to yield thioca
