6,6‐Dimethylfulvene reacts with LiPHMes (Mes = 2,4,6‐Me 3 C 6 H 2 ) to give Li[(C 5 H 4 )CMe 2 PHMes] ( 1 ). The ferrocene derivatives rac ‐[Fe{(η 5 ‐C 5 H 4 )CMe 2 PHR} 2 ] [R = Ph ( 2 ), Mes ( 3 )] are obtained in high yield from the lithium reagents Li[(C 5 H 4 )CMe 2 PHR] (R = Ph, Mes) and FeCl 2 . Compound 2 reacts with [Cp*TaCl 4 ] to give the heterotrinuclear complex rac ‐[Fe{(η 5 ‐C 5 H 4 )CMe 2 PHPh(Cp*TaCl 4 )} 2 ] ( 4 ). Compounds 1 − 4 were characterized spectroscopically, and crystal structure determinations were carried out on 2 − 4 . (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
