L'o-nitrobenzylidènediméthylsulfuranne: synthèse, réactivité

In aqueous solution, o-nitrobenzyldimethylsulfonium bromide and the corresponding ylid give, depending upon the conditions, o-nitrobenzyl alcohol, o-nitrobenzylsulfide, or methyl o-hydroxymethylbenzyl sulfide. The o-nitrophenyloxiranes may be obtained by the reaction of nitrobenzylidenedimethylsulfurane with aldehydes in a two-phase aqueous sodium hydroxide/dichloromethane system.
