Unprecedented Formation of Azulenylidene Ligands by Reaction of the Vinylidene Ligand in Arylvinylidene Pentacarbonyl Complexes of Chromium and Tungsten with Alkoxyacetylenes
the selectivity of the reactions is low; the isomeric ratio varies between 0.5 and 2 depending on the metal and the substituent. DFT calculations on the reaction mechanism indicate that the reactions are initiated by a nucleophilic addition of the terminal carbon atom of the alkoxyacetylene to the metal-bound Cα atom of the vinylidene ligand. The low selectivity of the reactions is in accord with the
亚芳基亚乙烯基(五羰基)铬和钨配合物[(CO)5 M C C(C 6 H 4 R 1 - p)R 2 ](M = Cr,W; R 1 = H; R 2 = Me,C 6 H 4 R 3 - p [R 3 = H,Me,OMe,Cl,t Bu]; R 1 = Me; R 2 = C 6 H 4 Cl- p)与烷氧基乙炔HC⋮COR'(R'= Et ,ŤBu,金刚烷基),通过将CC三键加到亚乙烯基配体上的1,3-和环扩环得到氮杂亚烯基络合物。当使用单取代和不对称的双取代的双(芳基)亚乙烯基络合物时,获得两种异构体的混合物。在两个异构体中,取代基要么连接到七元环上,要么位于苯基的对位。通常,反应的选择性低。根据金属和取代基的不同,异构体的比率在0.5和2之间变化。对反应机理的DFT计算表明,反应通过亲核加成中的烷氧基乙炔与金属结合的C中的末端碳原子的引发α亚乙烯基配体的原子。反应的低选择性符合计

The metal carbonyl anions [Fe(η-C5H5(CO)2]− and [Re(CO)5] undergo regio- and site-specific [2 + 2]-cycloadditions with the ketenimines Ph2CCNR (R = Me, Ph) to give the (isolable) anioniccomplexes [Ln(O)}]− (LnM = Fe(η-C5H5)CO, Re(CO)4) which have been alkylated and acylated at the exocyclic oxygen atom of the carbonyl function. The result is stable neutral complexes having a metallaazetidine structure
