The reaction of diphenyl methylphosphonate with lithium alkoxides gives phenyl alkyl methylphosphonates even with hindered alcohols and, in the case of chiral alcohols, with high diastereoselectivity at phosphorus. [Hydroxy(pho-sphoryloxy)X, iodo]benzenes 289, prepared from reactions of iodosobenzene with phosphonic or phosphinic acids react with ketones, esters or phenyl acetylene to give esters 290. Racemic l-hydroxy-4-(3-phenoxyphenyl)butylphosphonate diethyl ester undergoes stereoselective acetylation in the presence of a lipase to... 

Two convenient approaches to (diphenylphosphono)acetic esters (258) have been reported. One approach involves the reaction of chloroformate esters with the carbanion of diphenyl methylphosphonate and the other a Michaelis-Becker reaction of bromoacetic esters (Scheme 41) the former reaction gives better yields than the latter. Olefination reactions of (258) with benzaldehyde and... 

Condensation Polymerization of Phosphonate Esters or Diamides with Diamines and Related Reactions. Treatment of diphenyl methylphosphonate with diamines produces thermoplastic materials with elemental compositions corresponding to polymeric phosphonamides or imides (102,147,148).
