, p. 247 - 257 (2007/10/02)
Several phosphinites and phosphites, derived from chiral alcohols, were synthesized.The phosphinites were subjected to a I2-catalyzed Michaelis-Arbuzov rearrangement.Phosphinites derived from primary alcohols give satisfactory yields of the corresponding phosphineoxides.Phosphinites synthesized from secondary alcohols also undergo the rearrangement but numerous byproducts appear in the reaction mixtures.Optical resolutions of chiral phosphineoxides by crystallization with optically active acids were not successful.The corresponding phosphines can easily be prepared by reduction of the oxides with trichlorosilane.
