Abstract

Abstract Reaction between phosphoryl substrates,(EtO), P (O) X (X˭ H, R, OR) and dialkylaminoderivatives of Ti (IV), Ti (NR2) nCI4-n and Mn (NEt,), leads to the exchange of one or both EtO groups for the NR, substituent. The reactivity of the system depends on electronic, as well as steric, effects of both substrates, and approximately correlates with the Lewis acid-base interactions between the substrates, as measured by the ir spectroscopy.
