Reaction with sulfones

Substitution of sulfonesJ Organoaluminum reagents, particularly vinyl- or alkynylalanes, undergo Lewis acid catalyzed substitution reactions with sulfones. Thus the vinylalane 2 reacts with the allylic sulfone 1 in the presence of A1C13 to... [Pg.204]

Application of AT 3-carboxylic acid under standard conditions of TP synthesis (boiling acetic acid) usually leads to decarboxylation. This can be avoided, in the reaction with sulfon 24, by boiling the mixture in water (02S901). [Pg.151]

A new method for the preparation of PEMs is based on cross-linking and by thermally activated bridging of the polymer chains with polyatomic alcohols through condensation reaction with sulfonic acid functions. This was applied to sulfonated poly(ether ether ketone) (SPEEK) and some of the membranes exhibited conductivity higher than 2 x 10 S cm at room temperature. The SPEEK may potentially find applications as PEM materials for fuel cells. [Pg.408]

The concept of the conjugation reaction with sulfone 75 is presented in Equation 3.44. The nucleophilic addition of the heterocyclic nitrogen of the aromatic ring to the double bond affords intermediate 76, which upon elimination of tolyl-sulfinic acid forms a, 3-unsaturated ester 77. A second Michael addition finally gives cyclic bis-alkylated product 78 (Equation 3.44). [Pg.80]
