An economical way to obtain new monomers, precursors of electron transfer polymers, is described. These monomers were obtained by a Heck reaction between amino or halogeno-2,5-dimethoxydiarylmethane and methylacrylate. Different routes for the ionic reduction of various acetophenones to the corresponding diarylmethanes were studied. The yields and the nature of the by-products was stongly dependent
The reactions of o-lithiated O-aryl N,N-diethylcarbamates with different C–N multiple bond electrophiles have been thoroughly studied. A 1,5-O → N carbamoyl shift, a new variation of the anionic Fries-type rearrangement, takes place when nitriles, imines, or alkylcarbodiimides are employed. In these cases, the carbamoyl group plays a dual role as a directing group, building up a variety of functional
