REACTIONS WITH ELECTROPHILIC CARBON

Iodine acetate would seem to be unambiguously present in the iodination of pentamethylbenzene in acetic acid by iodine and mercuric acetate, since the latter components form an equilibrium mixture of iodine acetate and acetoxy-mercuric iodide and mercuric acetate speeds up the iodination332. Second-order rate coefficients of 0.078 (25 °C) and 0.299 (45 °C) were obtained, and these values are intermediate between those obtained for the reaction of bromine acetate with benzene (2.5 xlO-3) and toluene (1.2) at 25 °C, indicating that bromine acetate is the stronger electrophile. [Pg.139]

Radical-mediated Substitution Reactions. Furan undergoes substitution reactions with electrophilic carbon radicals to provide 2-aIkyl substituted furans (eq 6). These radicals are generated from dialkyl malonates with Ce" +, triethyl methanetricarboxy-late with Fe +/H202 in or ethyl iodoacetate... [Pg.335]

The nucleophilic reactivity of amines manifests itself in reactions with electrophilic carbon, as in haloalkanes, aldehydes, ketones, and carboxylic acids and their derivatives. [Pg.972]
