  通过钌催化的电子控制位点选择性功能化直接获得间烷基化 N-芳基唑盐：范围和机理方面

  摘要：

  有效获得具有不同立体电子特性的唑盐一直令有机金属化学家着迷。在此，我们描述了一种 Ru(II) 催化的一步获得多种间烷基化N-芳基（苯并）咪唑鎓盐（> 40 个例子）的方法，该策略从使用烷基溴的容易获得的唑鎓盐开始，通过σ-键活化策略。值得注意的是，本方法与多种唑鎓盐和仲/叔烷基溴兼容，包括生物学相关的基序。各种控制实验以及 DFT 计算建立了邻位金属化 Ru(II)-NHC 配合物 ( 6 ) 形成的反应途径，随后生成 Ru(III)-中间体，从而控制了观察到的反应间位选择性，通过单电子转移。至关重要的是，对反应机制的详细了解有助于理解为什么某些底物对该方法具有挑战性。

  A pigment dispersion comprising pigment, an aqueous carrier selected from water and a mixture of water and at least one organic solvent, and a pigment dispersant is described. The pigment dispersant is prepared by controlled radical polymerization, e.g., atom transfer radical polymerization, and has polymer chain structure represented by the following general formula I, &phgr;-(G) p -(E) s -T  I In general formula I, G is a residue of at least one radically polymerizable ethylenically unsaturated monomer; E is a hydrophilic residue of at least one radically polymerizable ethylenically unsaturated monomer; G and E are different from one another; &phgr; is a hydrophobic residue of or derived from the initiator, and is free of said radically transferable group; T is or is derived from the radically transferable group of the initiator; p and s represent average numbers of residues occurring in a block of residues; p and s are each individually selected such that the pigment dispersant has a number average molecular weight of at least 250.
