A method for obtaining a new class of pyrimidinium ylides (type 3) is presented. Their structures have been proved both by chemical and spectral methods (including two-dimensional experiments: 2D-COSY, 2D-HETCOR and 2D-HETCOR long range). The ability of the ylide to react with activated alkynes and alkenes has been studied. The ylide (3) could act as an initiator in anionic polymerisation leading to oligomers.
