✦ Synopsis

Diethylamides of Ti(IV), Mn(II), Sn(I1) and Sn(IV) are inert towards diethyl enzy phosphonate, but react easily with diethyl a-hydroxybenzylphosphonate with the exchange of one or two Et0 groups at phosphorus for diethylamino groups. We have recently found that dialkylamides of elements such as Ti(IV),l Mn(II),2 and Sn(I1) or Sn(IV)3 are capable of displacing the alkoxy (or aryloxy) substituents at the phosphoryl centre by a dialkylamino group (eq. 1).
