Abstract

The metathesis reaction of [W2(OtBu)6] with tBuCP leads to the phosphido complex [(tBuO)3WP] (1), which can be stabilized when the reaction is carried out in the presence of Lewis acidic carbonyl complexes of the type [M(CO)5thf] (M = Cr, W). However, further reaction of the metathesis products [(tBuO)3WCtBu] and [(tBuO)3WP→M(CO)5] [M = W (4a), Cr (4b)] with tBuCP leads after subsequent 1,3-OtBu ...
