, p. 219 - 221 (2007/10/02)
The reaction of substituted benzenesulfinic acids with N-phenylmaleimide has been carried out, and the products obtained have been identified as sulfones from analyses of their IR, UV, and NMR spectra. From the kinetic investigation, a linear Hammett relationship between the sigma -value and log K//2/K//0 has been confirmed. It is concluded that the nucleophilic attack of the sulfinic acid sulfur atom on the carbon of the C equals C bond of N-phenylmaleimide is the rate-determining step.

Reaction of pyridinium p-toluenesulfonylmethylide with N-substituted maleimides in the presence of primary or secondary amines gives aminomethylenesuccinimides (4).The geometry of these enamines is presented.In one case, the E- and Z-isomers have been sep
PYRIDINIUM p-TOLUENESULFONYLMETHYLIDE AS A FORMYL ANION EQUIVALENT
Abramovitch, Rudolph A.,Mathur, Suchet S.,Saunders, Daniel W.,Vanderpool, Danny P.
, p. 705 - 708 (2007/10/02)
Pyridinium p-toluenesulfonylmethylide serves as a formyl anion equivalent and, in the presence of an alcohol, undergoes 1,4-addition to N-substituted maleimides to give alkoxy- (or aryloxy)-methylene-succinimides.The protected aldehyde group can be libera
