  摘要：

  1-炔基-二甲基（三有机膦）金（III）的类型的复合物的顺式-Me 2（PH 3 P）的Au-CC-R，其中R = H，Me中，Ph（上1 - 3）已经从制备顺式- Me 2（Ph 3 P）AuX（X = Cl，I）络合物和锂炔基。已确定1和2的晶体结构以及参考化合物cis -Me 2（Ph 3 P）AuX（X = Cl，I）和cis -Me 2（Me 3P）AuI。分子具有标准的正方形平面几何形状，并且不缔合为低聚物。由于碳轨道的杂化程度不同，发现Au-C（CR）键明显短于Au-CH 3键。化合物1 - 3是稳定的无色，在20℃的结晶固体，但分解与选择性的（加热顺式）的金的乙烷和形成还原消除（I）的炔基（PH 3 P）的Au-CC-R这样保持强金-炔键。还可以通过常规方法由（R 3 P）AuX配合物和（Me 3 P）Au–CC–Ph和[（p -Tol）3 P] Au–CC–H已确定。具有小Me

  The reactions of halo-alkynes Cl-C CH, C-lCl C-Cl or PhC C-I with solutions of Li+[MeAuMe](-) in diethylether containing Ph3P do not give the expected oxidative addition products Me-2(RC C)Au(PPh3) with R = H, Cl, Ph. A mixture of other complexes is obtained instead which are generated in secondary reactions involving reductive elimination of ethane and/or dialkyne. However, addition of the halo-alkene H(Cl)C=CCl2, to the same substrate solution affords trans-Me-2[trans-H(Cl)C=C(Cl)]Au(PPh3) in good yield. Its molecular structure with pseudo-C-s symmetry has been determined by the solution NMR spectra and a single-crystal X-ray diffraction study. The reaction of methyl iodide with solutions of Li+[RC CAuC CR](-) in diethylether containing PPh3 give the quaternary salts Ph3PMe+. [RC CAuC CR](-) as the main products and only small amounts of cis-Me-2(RC C)Au(PPh3) complexes probably formed in a series of oxidative addition, reductive elimination, and substitution reactions. The structure of Ph3PMe+ [PhC CAuC CPh](-) has been determined. (c) 2006 Elsevier B.V. All rights reserved.
