  Organoaluminium(III) thioetherbis(phenolate) complexes derived from 2,2′-thiobis(4,6-diterbuthylphenolate) (Stdiol) and 2,2′-thiobis(4,6-dimethylphenolate) (Smdiol) were prepared by reaction of AlMe3 with the diol proligands LH2 (SmdiolH2, StdiolH2). Monomeric complexes of general formulae [LAlR(L′)] (L = Stdiol, R = Me, L′ = THF (1); L = Stdiol, R = Me, L′ = Et2O (2); L = Stdiol, R = iBu, L′ = THF) (3); L = Smdiol, R = Me, L′ = THF (4); L = Smdiol, R = iBu, L′ = THF (5)) and [LAlCl(THF)] (L = Stdiol (6); L = Smdiol (7)) were obtained when the reactions were performed in THF or Et2O in hexane or toluene, species of formulae [(L2Al)AlR2] (L = Stdiol, R = Me (8); L = Stdiol, R = iBu (9); L = Smdiol, R = Me (10)) were formed as evidenced by spectroscopic methods. Crystals suitable for X-ray diffraction studies were obtained for 2, 3, 4, 6, 8, 9 and 10. In these cases the sulfur atom coordinates to the aluminium center with Al–S bond lengths between 2.43–2.75 Å adopting boat–boat conformations. Compounds 1, 3, 4, and 8 were tested in the catalytic Diels–Alder cycloaddition reaction between methacrolein and cyclopentadiene showing excellent regioselectivities with good conversion yields.

  通过 AlMe3 与二元醇原基 LH2（SmdiolH2、StdiolH2）的反应，制备了 2,2â²-硫代双（4,6-二丁基苯酚）（Stdiol）和 2,2â²-硫代双（4,6-二甲基苯酚）（Smdiol）的硫醚双（苯酚）有机铝（III）络合物。通式为[LAlR(Lâ²)]的单体复合物（L = Stdiol，R = Me，Lâ² = THF (1)；L = Stdiol，R = Me，Lâ² = Et2O (2)；L = Stdiol, R = iBu, Lâ² = THF) (3); L = Smdiol, R = Me, Lâ² = THF (4); L = Smdiol, R = iBu, Lâ² = THF (5)) 和 [LAlCl(THF)] (L = Stdiol (6)；当反应在己烷或甲苯中的 THF 或 Et2O 中进行时，可得到[(L2Al)AlR2]（L = Stdiol，R = Me (8)；L = Stdiol，R = iBu (9)；L = Smdiol，R = Me (10)），并通过光谱方法证明形成了[(L2Al)AlR2]（L = Stdiol，R = Me (8)；L = Stdiol，R = iBu (9)；L = Smdiol，R = Me (10)）。2、3、4、6、8、9 和 10 的晶体适合进行 X 射线衍射研究。在这些情况下，硫原子与铝中心配位，AlâS 键长度在 2.43â2.75 Ã 之间，采用舟形构象。化合物 1、3、4 和 8 在甲基丙烯醛与环戊二烯的催化 DielsâAlder 环加成反应中进行了测试，结果表明其具有极佳的区域选择性和良好的转化率。
