Phosphinoenolato complexes

Olefin Process (SHOP). Although this Ni complex is prepared by oxidative addition reaction (Section II.B.4), most other phosphinoenolato complexes are prepared by deprotonation of the corresponding phosphines R3PCH(R )C(0)R" or by other methods, as discussed in Sections III.A and IV.A. 

The coordination chemistry of phosphinoenolato complexes has been reviewed. In certain cases the phosphinoenolate complex acts as a plain phosphine hgand for example. 

The reaction between the phosphinoenolato complexes 161, Me3SiC=CH and NTLjPFe in methanol gives the corresponding metalafuran complexes 162 through the intermediates... 

Phosphinoenolato complexes 174a-b react with Ph2PCl to afford 175a-b, respectively, while 176 gives 177 . Complex 174a or 178 reacts with PhPCl2 in the presence of py to give 179 or 180, respectively . ... 

Phosphinoenolato complexes 181 and 181 react with Me02CC=CC02Me to give 182 and 182, respectively . Complexes 183 react with terminal alkynes R"C=CH and PFe in methanol to give complexes 184 PFe, although when /7 -arene = MesH, CeMee, R = Me, R = f-Bu and R" = MesSi a different type of product, 185-PF6, forms instead . ...
