η-Cyclopentadienyltungsten compounds with vinyl- and allyl-phosphine ligands
Abstract
The properties as ligands of the primary phosphines PH2(CHCH2)1 and PH2(CH2CHCH2)2 have been studied. The new compounds [W(η-C5R5)Cl4(PH2R′)](R5= H4Pri, R′= CHCH27 or CH2CHCH28; R5= Me4Et, R′= CHCH29 or CH2CHCH210), [W2(η-C5H4Pri)2X4(µ-H)(µ-PHR)](X = Cl, R = CHCH212 or CH2CHCH213; X = Br, R = CHCH215), [W2(η-C5Me5)2Cl4(µ-H)(µ-PHC2H3)]17 and [W2(η-C5Me5)2Cl2(µ-Cl)(µ-PHC2H3)]18 have been prepared. The crystal structures of compounds 10 and 17 have been determined.
