Abstract

Treatment of dialkyl aryl phosphates with n-butyllithium or lithium diisopropylamide results in a rearrangement that involves the fission of an oxygen-phosphorus bond and formation of a CP bond yielding dialkyl (2-hydroxyary1) phosphonates. A dialkyl (2-hydroxyary1) phosphonat. e on reaction with dialkyl phosphorochloridate yields a phosphate- phosphonate which on treatment with lithium diisopropylamide gives a tetraalkyl (2- ...
