  Reactivity of (Me3Al)2 with selected aminoarsines and secondary amines

  摘要：

  The reactions of (Me3Al)2 with 11 aminoarsines, Me2AsR (R = Et2N, Prn2N, Pri2N, Bun2N, Bui2N, C4H10N, C5H10N, C6H12N, CH3NC4H8N, Ph2N and Bzl2N, where Bzl = PhCH2-), have been studied by multinuclear NMR spectroscopy. The results are compared with those of our previous studies on the Me3Al/Me2AsNMe2 system. In each case, except Me2AsNPh2, the final reaction products are [Me2AlR]2 and Me3As. The reaction intermediates have been identified and, in most cases, the As-N-Al adducts and Me2AlR . AlMe3 are observed. With Me2AsNPh2 the product is Me3As . Me2AlNPh2. The influence of steric and electronic effects on arsenic vs nitrogen bonding site preference, adduct stability, complexity of overall reaction and ease of forming Me3As and [Me2AlR]2 are discussed. [Me2AlR]2, Me2AlR . AlMe3 and Me3Al . HR have been independently synthesized and characterized. A comparison of the C-13 NMR chemical shift values for Me2AsR and Me2AsR-AlMe3 provides information on steric interactions that influence adduct stability.

  Steric factors govern the formation of half-sandwich complexes (C5Me4R)Ln[N(SiHMe2)2]2 according to acid-base reactions utilising Ln[N(SiHMe2)2)3(thf)2 and substituted cyclopentadienes. Subsequent trimethylaluminium-promoted silylamide elimination produces the first half-sandwich bis(tetramethylaluminate) complexes (C5Me4R)Ln(AlMe4)2.

  根据使用Ln [N（SiHMe2）2）3（thf）2和取代的环戊二烯的酸碱反应，控制立体因素控制半三明治复合物（C5Me4R）Ln [N（SiHMe2）2] 2的形成。随后的三甲基铝促进的甲硅烷基酰胺消除反应产生了第一个半三明治双（四甲基铝酸酯）配合物（C5Me4R）Ln（AlMe4）2。
