Transition metal-substituted phosphaalkenes. 42 reactivity of the ferriophosphaalkenes [(η5-C5Me5)(CO)2FeP=C(NR 12)R2] (NR12 = NMe2, NC5H10, R2 = Ph, tBu) towards protic acids, alkylation reagents, and [{(Z)-cyclooctene}Cr(CO)5]

The reaction of equimolar amounts of [(η5-C5Me5)(CO)2FeP=C(NR 12)R2] (2a: NR12 = NMe2, R2 = Ph; 2b: NMe2. fBu; 2c: NC5H10, Ph) and etherial HBF4 gave rise to the formation of [(η5-C5Me5)(CO)2FeP(H)C(NR 12)R2] (BF4) (3 a-c) which were isolated as light red powders. Compounds 2a-c were converted into [(η5-C5Me5)-(CO) 2FeP(Me)C(NR12)R2] (SO3CF3) (4a-c) by treatment with methyl trifluoromethane sulfonate. In addition 2a and Me3SiCH2OSO2CF3 afforded light red [(η5-C5Me5)-(CO)2FeP(CH 2SiMe3)C(NMe2)Ph](SO3CF3) (5). The black complex [(η5-C5Me5)(CO)2FeP{Cr(CO) 5)C(NMe2)Ph] (6) resulted from the combination of 2a with [{(Z)-cyclooctene}Cr(CO)5]. The novel products were characterized by elemental analyses and spectra (IR, 1H-, 13C- und 31P-NMR).
