Abstract A series of substituted-cyclopentadienyl molybdenumallylderivatives has been prepared by reacting (η 3 -C 3 H 5 ) 3 MoCl with substituted-cyclopentadienyl and -indenyl alkali metal salts. In general, the isolated products are of the type Cp′Mo(η 3 -C 3 H 5 ) 2 and in three cases this has been confirmed by crystal structure determinations. Spectroscopic evidence suggests that at low temperatures
摘要通过使(η3 -C 3 H 5)3 MoCl与取代的环戊二烯基和-茚基碱金属盐反应,制备了一系列的取代环戊二烯基钼烯丙基衍生物。通常,分离出的产物为Cp'Mo(η3 -C 3 H 5)2类型,这在三种情况下已通过晶体结构测定得到证实。光谱证据表明,在低温下还形成了具有Cp'Mo(η3 -C 3 H 5)2(η1 -C 3 H 5)组成的化合物。与芴基钾的反应是反常的:NMR光谱和晶体结构确定表明,产物(η3-芴基)Mo(η3 -C 3 H 5)3包含四个与金属不对称键合的η3-烯丙基原子。

The thermal average molecularstructure of Tl(C5Me5) has been determined by gasphase electron diffraction (GED). The molecule has a half sandwich structure of C5v symmetry. The TlC bond distance is 266.3(5) pm, with a root-mean-square amplitude of vibration (l-value) of 5.2(24) ppm. The results indicate that the methyl groups of the ring tend to decrease the thalliumcarbon bond distance compared
T1(C 5 Me 5)的热均分子结构已经通过气相电子衍射(GED)确定。该分子具有C 5 v对称的半夹心结构。T1C键合距离为266.3(5)pm,振动的均方根振幅(l值)为5.2(24)ppm。结果表明,与未甲基化的化合物相比,环的甲基倾向于减小decrease碳键的距离。

The crystal structure of TlC5Me5 (I), obtained from Tl2SO4 and NaC5Me5, has been determined. I crystallizes in the space group Pc (Z = 2) with a 1086(1), b 1089(1), c 1458(1) pm and β 110.3(1)°; it forms a polymeric zig-zag chain structure similar to that of TlC5H5 but with much shorter TlTl distances which is indicative of a higher degree of covalent bonding. 1H and 13C NMR data are reported.
已经确定了从Tl 2 SO 4和NaC 5 Me 5获得的TlC 5 Me 5(I)的晶体结构。我结晶空间群中的PC(ż与= 2)一1086(1),b 1089(1),Ç 1458(1)时,β110.3(1)°; 它形成类似于TlC 5 H 5的聚合物之字形链结构,但具有更短的TlTl距离,这表明较高的共价键合度。报告了1 H和13 C NMR数据。

as H2Al(OCH2CH2OMe)2− to give (eq. 3) the CS cleaved butadiene-thiolate product 3. Subsequent reactions of 3 are shown: This scheme is not intended to indicate that all reactions were performed on the thiophene complex; many were carried out using the methyl-substituted thiophene analogs. Structures of complexes of the types 6 and 9 were established by X-ray diffraction studies. Possible mechanisms
