TS of phosphite anions addition reactions



 Hi all,
 does anyone have informations about calculations of TS of phosphite anion
 addition to C=X bonds (X = O,N) using semiempirical methods ? Any
 information would be greatly appreciated.
 Furthermore any references to semiempirical calculations on phosphite
 anions and derivatives would be most welcome.  I will summarize the
 responses to the net.
 Thanks in advance to all responders,
 Harald
