  “Constrained geometry” catalysts of the rare-earth metals for the hydrosilylation of olefins

  摘要：

  A series of yttrium and lutetium alkyl complexes [Ln(eta(5)-C(5)Me(4)ZNR'-kappa N)(CH2SiMe3)(THF)(n)] (Ln = Y, Lu) was prepared by reacting the tris(trimethylsilylmethyl) precursor [Ln(CH2SiMe3)(3)(THF)(2)] with different linked amino-cyclopentadienes of the type (C5Me4H)ZNHR' (Z = SiMe2, CH2SiMe2; R'= tBu, Ph, C6H4-tBu-4, C6H4-nBu-4). The catalytic activity of these alkyl complexes in the hydrosilylation of 1-decene and styrene using PhSiH3 as reagent was examined under standard conditions. A significant influence of the ligand structure on the catalytic property (turnover frequency, regioselectivity) was observed with the yttrium. complex [Y(eta(5)-C(5)Me(4)CH(2)SiMe(2)NtBu-kappa N)(CH2SiMe3)(THF)] being the most active for 1-decene hydrosilylation.

  the reaction. Therefore, this catalyst system works homogeneously but can be separated and reused, thus constituting the first example of a recyclable catalyst system for the dimerization of terminal alkynes and also the first example of (Z)-selective head-to-head dimerization of aromatic terminal alkynes.

  通过使用半茂金属镥烷基配合物 Me2Si(C5Me4)(NAr)Lu(CH2SiMe3)(THF) (Ar = Ph, C6H3Me2 -2,6, C6H2Me3-2,4,6) 作为催化剂。众所周知，芳香族 C-Cl、C-Br 和 CI 键极易受到过渡金属的还原裂解，但在本反应中幸存下来。相应的二聚炔化物 [Me2Si(C5Me4)(NAr)Lu(mu-CCR)]2 被认为是真正的催化剂，其中一些已被分离并进行结构表征。这些炔化物物质在反应温度（80-110 摄氏度）下是热稳定的并且可溶，但它们在反应完成后冷却至室温时会沉淀。因此，该催化剂体系工作均匀，但可以分离和重复使用，
