Electrophilic reactions magnesium compounds

Metal-halogen exchange can be achieved in the formation of 3-lithio-l-methylpyrazole from the bromo-pyrazole, and reaction of 4-bromopyrazole with two equivalents of n-butyllithium produces a 1,4-dilithio-pyrazole that reacts with electrophiles at C-4. ° 4-Iodoisothiazole can be converted into a magnesium compound that shows normal nucleophilic Grignard properties. ... [Pg.490]

Magnesium alkyUdene carbenoids were found to be reactive with different nucleophiles to give new alkenyhnagnesium compounds which could be trapped with electrophiles. As a whole, novel methods for the synthesis of tri- or tetrasubstimted olefins from the 1-chlorovinyl p-tolyl sulfoxides in a one-pot reaction are realized. [Pg.755]
