Nucleophilic substitution process synthetic strategies

Several unique synthetic strategies for bidentate(amino)(oxy)- and (amino)(aryl) carbenes have been described (Scheme 10). For the former, the reaction of the amino(phosphino)carbene with an ort/io-quinone leads to the transient formation of a zwitterionic species featuring both a phosphonio nucleofuge and an aryloxide nucleophile that allow for a subsequent intramolecular substitution process. The... [Pg.141]

Syntheses and properties of PES s were explored in the 1960 s by Union Carbide (USA), 3 M Corp (USA), and ICl pic (UK) [99-101]. Nearly at the same time. Two quite different synthetic strategies were elaborated, namely a Friedel-Crafts type polysulfonylation process (see Formula 6.5) and a nucleophilic substitution of 4,4 -... [Pg.84]
