oxidative addition of MeI to [Rh(C(5)H(4)(CH(2))(2)PEt(2))(CO)] and [Rh(Cp'(CH(2))(2)PPh(2))(CO)] are 62 and 1770 times faster than to [Cp*Rh(CO)(2)]. Methyl migration is slower, however. HighpressureNMRstudies show that [Co(Cp'(CH(2))(2)PEt(2))(CO)] and [Cp*Rh(PEt(3))(CO)] are unstable towards phosphine oxidation and/or quaternisation under methanol carbonylation conditions, but that [Rh(Cp'(CH(2))(2)PEt(2))(CO)]

Polysubstituted cyclopentadiene-containing compound, in which at least one substituent is of the form -RDR'n, in which R is a linking group between the cyclopentadiene and the DR'n group, D is a hetero atom selected from group 15 or 16 of the Periodic System of the Elements or an aryl group, in which case R has at least the length of an ethylene group, R' is a substituent and n is the number of R' groups bound to D.
Metal complexes in which at least one of these cyclopentadiene compounds is present as a ligand are useful as catalysts for the polymerisation of alpha-olefins.
多取代环戊二烯化合物,其中至少有一个取代基为 -RDR'n 形式,其中 R 是环戊二烯与 DR'n 基团之间的连接基团,D 是选自元素周期系第 15 或 16 族的杂原子或芳基,在这种情况下,R 至少具有乙烯基的长度,R'是取代基,n 是与 D 结合的 R' 基团的数目。
含有至少一种环戊二烯化合物作为配体的金属复合物可用作α-烯烃聚合的催化剂。
