The reaction of the niobocene complex [Nb(η 5 ‐C 5 H 4 SiMe 3 ) 2 (PPh 2 )(L)] {L = CO ( 1 ), CNXylyl ( 2 ), and CNCy ( 3 )} with isothiocyanates RNCS (R = t Bu or Ph) yielded new derivatives [Nb(η 5 ‐C 5 H 4 SiMe 3 ) 2 {κ 1 ‐ S ‐SC(PPh 2 )(=NR)}(L)] {R = t Bu, L = CO ( 4 ), CNXylyl ( 5 ); R = Ph, L = CO ( 6 ), CNXylyl ( 7 ), CNCy ( 8 )} by the insertion of the isothiocyanate group into the niobium–phosphorus bond of the phosphide ligand. Dinuclear complexes were also obtained by the reaction of complexes 1 – 3 with phenyldiisothiocyanate {1,4‐(SCN) 2 C 6 H 4 } to yield [{Nb(η 5 ‐C 5 H 4 SiMe 3 ) 2 (L)} 2 {μ‐(κ 1 ‐ S ‐1,4‐SC{PPh 2 }{=N}) 2 (C 6 H 4 )}] {L = CO ( 9 ), CNXylyl ( 10 ), CNCy ( 11 )}.(© Wiley‐VCH Verlag GmbH & Co.
