Reactivity of a phosphido-niobocene derivative toward CS2 and alkyl halides to give phosphinodithioformato- and phosphino-niobocene complexes: X-ray crystal structures of [Nb(η5-C5H 4SiMe3)2(κ1-S-SC(S)(PPh 2))(CO)]

The reaction of the niobocene complex [Nb(η5-C 5H4SiMe3)2(PHPh2)(CO)]Cl (1) with NaOH yielded the corresponding phosphidoniobocene derivative [Nb(η5-C5H4SiMe3) 2(PPh2)(CO)] (2) by deprotonation of the P-H bond. The subsequent insertion reaction of carbon disulfide into the Nb-P bond yielded the first examples of a diphenylphosphinodithioformato ligand coordinated to the niobocene system by giving [Nb(η5-C5H 4SiMe3)2(κ1-S-SC(S)(PPh 2))(CO)] (3) and [Nb(η5-C5H 4SiMe3)2(κ2-S,S-SC(S)(PPh 2))] (4); the latter compound can also be prepared by the corresponding CO elimination of 3. The cationic d2 species [Nb(η5-C5H4SiMe3) 2(PRPh2)(CO)]X (R = Me, X = I (5); CH2Ph, X = Br (6); CH2CH2Ph, X = Br (7)) were prepared by the reaction of alkyl halides RX (R = Me, X = I; CH2Ph, X = Br; CH 2CH2Ph, X = Br) with 2 by electrophilic attack on the phosphorus atom present in the phosphido terminal ligand. In the same way, the reaction of 2 with ICH2CH2I yielded the complex [Nb(η5-C5H4SiMe3) 2(P(I)Ph2)(CO)]-I3 (8). The molecular structures of 3 and 8 were determined by single-crystal X-ray diffraction studies.
