Abstract

The niobium phosphido complex [Nb(η5-C5H4SiMe3)2(CNXylyl)(PPh2)] (2) undergoes an unusual cycloaddition reaction with electron-deficient alkynes to give the novel five-membered heteroniobacycles [Nb(η5-C5H4SiMe3)2(κC-C([double bond, length as m-dash]N(Xylyl))C(CO2Me)[double bond, length as m-dash]C(R)PPh2-κP)] (R = H 3 and R = Me 4).
