Abstract

The reactions of phenacyl benzoates, X–C 6 H 4 COCH 2 OCOC 6 H 4–Y (1a–i), with trialkyl phosphites (2a–c) giving dialkyl 1-arylvinyl phosphates (3a–d) in high yields were studied kinetically using the GLC technique. The overall reactions are second order, and exhibit a moderate solvent effect and catalysis upon the addition of certain organic acids. The activation energy, E a= 16.5 kcal/mol, and entropy, ΔS\ neweq=− 38.5 eu, were obtained ...
