V. Lucchini et al., THIIRANIUM AND THIIRENIUM IONS - FROM REACTION INTERMEDIATES TO BUILDING-BLOCKS IN ORGANIC-SYNTHESIS, Gazzetta chimica italiana, 127(4), 1997, pp. 177-188
The chemistry of thiiranium and thiirenium ions, examples of iranium a
nd irenium ions, is discussed in the light of recent reactivity data o
btained on isolated ions. An overview of the use of thiiranium and sel
eniranium ions in organic synthesis as useful building blocks to contr
ol the regio- and the stereochemistry of several processes is presente
