    之二的制备(η 3 -烯丙基)铁(II)络合物及其反应用的1,3-二烯
    摘要:
    The title compounds were prepared by treating Fe(PR(3))(2)Cl-2 or Fe(R(2)P(CH2)(n)PR(2))Cl-2 with allylmagnesium chloride. Some of them were also made by reaction of Fe(PR(3))(2)Cl-2 with isopropylmagnesium chloride, or with active-magnesium and allyl chloride, or by reaction between tris(eta(3)-allyl)iron and bis(dimethylphosphino)ethane. The new compounds were characterized by NMR spectroscopy and shown to be formed as a mixture of two isomers that differ in the mutual arrangement of the two allyl groups. The reactions of the bis(allyl)iron compounds with 1,3-dienes were studied: complexes containing eta(4)-1,3-C4H6, eta(4)-1-C3H5C4H5 or eta(5)-l-ethylcyclohexadienyl groups were isolated from the reaction with 1,3-butadiene. The reaction between (eta(3)-C3H5)(2)Fe((Pr2PC2H4PPr)-Pr-i-Pr-i(2)) and 1,3-cyclohexadiene gave (eta(5)-cyclohexadienyl)Fe((Pr2PC2H4PPr2)-Pr-i-Pr-i)H.

    Analytical and Mössbauer spectral data show that Ph2PCH2CH2PPh2(dppe) forms adducts [FeCl2(dppe)] and [FeI2(dppe)], and that [FeCl2(dppe)2] does not exist. The phosphine 1,2-C6H4(PPh2)2(opdp) forms adducts FeX2(opdp)2, which exists in one form (high-spin, trans octahedral) for X = Cl, and in two isomeric forms for X = Br or I. One isomer for X = I is high-spin, trans octahedral, and the other is ionic
    分析和Mössbauer光谱数据表明,Ph 2 PCH 2 CH 2 PPh 2(dppe)形成加合物[FeCl 2(dppe)]和[FeI 2(dppe)],并且不存在[FeCl 2(dppe)2 ]。膦1,2-C 6 H 4(PPh 2)2(opdp)形成加合物FeX 2(opdp)2,对于X = Cl,它以一种形式(高旋转,反八面体)存在,并且以两种异构体形式存在。对于X = Br或I。对于X = I的一个异构体是高自旋,反式八面体,另一个是离子低旋和五坐标。将这些结构及其Mössbauer光谱与Me 2 PCH 2 CH 2 PMe 2,Et 2 PCH 2 CH 2 PEt 2,Pr i 2 PCH 2 CH 2 Pr i 2和Ph 2 PCH的衍生物进行了比较。2 PPh 2。

Along the same line, 1,3-dienes bind well to 2 but undergo spontaneous activation if allylic C–H bonds are present; the resulting hydride is transferred to a residual ethylene ligand, as manifest in the formation of the cyclopentadienyl ethyl complex 22.

The resulting complex has a diene dihydride character in solution (15), whereas its structure in the solid state is more consistent with an η3‐allyl iron hydride rendition featuring an additional agostic interaction (14). Finally, the preparation of the cyclopentadienyl iron complex 25 illustrates how an iron‐mediated C–H activation cascade can be coaxed to induce a stereoselective CC bond
    用含β-氢原子的格氏试剂对配合物2和7进行烷基化对于理解CH活化以及由低价铁物种介导的CC键形成具有重要意义。具体来说,在乙烯气氛下2与EtMgBr的反应提供了双乙烯配合物1,该配合物是原型[2 + 2 + 2]环加成反应的活性预催化剂,并且是进行机理研究的有价值的探针。通过将其转化为双炔烃配合物6可以说明这一方面,这是负载有两个底物分子的环加成催化剂的空前表现。另一方面,2的烷基化用1当量的环己基溴化镁提供的独特的烷基铁种类11具有14电子计数,其具有不少于4个β-H原子,但在低温下对消除β-氢化物稳定。相反,用环己基溴化镁对1进行彻底的烷基化会触发由单个铁中心介导的两个连续的C–H活化反应。将得到的复合物在溶液(a二烯二氢化字符15),而其在固态结构是具有η更一致的3 -烯丙基铁氢化再现设有一个额外的抓氢键(14)。最后,制备环戊二烯基铁络合物25说明了如何介导铁介导的C–H激活级联以
