Abstract
Synthetic studies have been carried out for the addition or substitution of phosphorus nucleophiles to the cation [(exo-6-R-η 5-2-MeO-C6H5)Mn(CO)2NO]PF6, 2. PPh3 reacts with 2 to yield the CO displaced product and MePPh2 attacks the dienyl ring of 2 to yield the phosphonium adduct or the metal to give the CO displaced depending upon the reaction temperatures. Nucleophilic addition of HPPh2 to the dienyl ring of 2 gives a neutral substituted product. P(OMe)3 reacts with 2 to yield a mixture of ring adduct and CO displaced product at room temperature. At - 20℃, P(OMe)3 attacks the dienyl ring of 2 to give a posphonium adduct, which underwent Arbuzov reaction. This reaction affords a new route to the phosphonate complexes.
