STABLE CARBON-YLIDES

5-Acylmethylene-1,2,4-triazolium salts were synthesized and converted to stable anhydrobases by aqueous alkali.The close analogy of their spectra with those of phosphorus-ylides and their reactions suggest that the anhydrobases may be regarded as carbon-ylides. α,β-Unsaturated aldehydes were synthesized in moderate yield by selective reduction of the salts folloved by acid hydrolysis.
