Preliminary chemical study of (2-oxo-1,2-dihydrophosphete(P-W))pentacarbonyltungsten complexes

Marinetti, Angela,Mathey, Fran?ois

, p. 633 - 637 (1988)

The chemistry of the new four-membered 2-oxo-1,2-dihydrophosphete ring has been investigated in two P-W(CO)5 complexes. All reactions which have been observed take place at the P-C(O) bond. Hydrolysis gives the corresponding open-chain carboxyl
