Abstract:
A one-pot synthesis of sterically congested phosphorus ylides in fairly high yields by the reaction of 2,2,6,6-tetramethyl-3,5-heptanedione, dialkyl acetylenedicarboxylates and triphenylphosphine is reported. The structures of these compounds were confirmed by IR, 1 H, 31 P and 13 C NMR spectroscopy, and X-ray single crystal structure determination. The NMR spectra (CDCl3 as solvent) indicated that the compounds contained two rotamers for each ylide.
