    摘要:
    氢氧根离子与(CO)5 MoC(XCH 2 CH 2 OH)(C 6 H 5)(X = O表示Mo–OR,X = S表示Mo–SR)和(CO )报告了5 WC(OCH 2 CH 2 OH)(C 6 H 4 -Z)(W-OR(Z))。结果与碱性溶液中的一条途径一致,该途径涉及OH基团的快速去质子化,然后进行限速环化。W–OR(Z)反应的参数k 1 K OH根据苯基取代基确定官能度。发现它们与哈米特方程很好地相关。反应性对配合物M–OR(M = Cr,Mo和W)中金属原子的依赖性表明,在元素周期表中,反应性略有下降,而在M–SR中,反应性略有下降。 。这些结果的合理解释是根据金属原子的电负性值提供的。W-OR(Z)比W-SR(Z)高得多的ρ(k 1 K OH)值主要是由于氧对硫的更强的π-给体效应使反应物卡宾配合物稳定所致。

  • Reactions of Group 6 Fischer carbene complexes with alkynes: effect of the metal on the product distribution and the isolation of a nontautomerized cyclohexadienone complex
    作者:William D. Wulff、Brian M. Bax、Timothy A. Brandvold、Kin Shing Chan、Adam M. Gilbert、Richard P. Hsung、John Mitchell、Jon Clardy

    日期:1994.1
    The first comparative study on the effect of the nature of the metal on the reactions of unsaturated group 6 Fischer carbene complexes with alkynes is reported. The scope of the study includes both aryl- and alkenylcarbene complexes of chromium, molybdenum, and tungsten for both internal and terminal alkynes. Twenty-one different organic structural types have been isolated and characterized from these reactions, but in most instances phenols and indene (cyclopentadiene) products are the two most frequently observed. The general observation made is that phenol formation is favored over indene (cyclopentadiene) formation in the order chromium > tungsten > molybdenum. The effect of the concentration of the alkyne on the distribution between phenol and indene (cyclopentadiene) was also examined and was found to be most prevalent in the order molybdenum > chromium > tungsten. The bis(alkyne)(eta4-cyclohexadienone)molybdenum complex 107 has been isolated in which the final tautomerization to the phenol product has not occurred. This complex has been characterized by X-ray diffraction and provides support for the previous interpretations of the concentration effects for the reactions of chromium complexes. This complex is the first example of the long-proposed ultimate intermediate in these reactions. Crystal data for 107: space group P2(1)/c, Z = 4, a = 19.088(4) angstrom, b = 10.101(1) angstrom c = 14.578(3) angstrom, a = 90.0-degrees, beta = 109.917(13)-degrees, gamma = 90.0-degrees, R = 0.0598, and R(w) = 0.0788 for the 2405 reflections observed.
