Sandmeyer‐type stannylation: Stille coupling is one of the most powerful coupling reactions for CC bond formation, whereas there are only limited methods to access aryl stannane compounds. A mild stannylation process based on a Sandmeyer‐type transformation using aromatic amines as the starting materials is described. DCE: 1,2‐dichloroethane.

of different γ-oxo α-amino acids from hexafluoroacetone protected L-aspartic acid chloride 1 via Stille cross coupling reaction is described. Stille reaction of 1 with vinyltributyltin followed by Lewis acid catalyzed intramolecular Michael addition provides access to 4-substituted pipecolicacidderivatives.

of the insertion of sulfurdioxide into the aryl carbon—tin bond of a species of 3- and 4-substituted phenyltrimethyl stannanes in anhydrous methanol has been conducted. The reaction is cleanly second order in this solvent (first order in each of stannane and sulfurdioxide) and the second order rate constants show an excellent correlation with σ+, indicating an electrophilic insertionreaction.

Kinetic studies of the reaction between the organometallic complex [Ru(CO)3(1–5-η-C6H7)]BF4(1) and aryltrimethyl-silanes and -stannanes of the type XC6H4M′Me3(M′= Si or Sn; X = H, 4-NMe2, 4-OMe, 1 -OMe, 4-Me, 4-SMe, 4-F, 4-Cl, 4-Br, 3-F, or 3-CF3) reveal the rate law, rate =k[ Ru][XC6H4M′Me3]. This rate law has been rationalised in terms of a rate-determining electrophilic attack by complex (1) on

initial tin–alkali metal exchange or an electron-transfer forming aryl anions and distannanes which subsequently react to the substitution products. Aryl radicalintermediates by an electron-transfer process are also important in the reactions of trialkylstannane anions with electron-withdrawing groups-substituted arylstannanes, 1-naphthylstannanes, diphenylstannanes, and triphenylmethylstannane as good
研究了三烷基锡烷阴离子 R3Sn− 与芳基锡烷 ArSnR3' 的反应;三烷基锡烷阴离子与芳基锡烷在 50 °C 下以良好的产率得到取代产物 ArSnR3。当用于捕获游离阴离子的叔丁胺存在于反应混合物中时,这些取代产物中的大多数被转移到还原产物 ArH。这些结果与最初的锡碱金属交换或电子转移形成芳基阴离子和二锡烷一致,随后与取代产物反应。通过电子转移过程产生的芳基自由基中间体在三烷基锡烷阴离子与吸电子基团取代的芳基锡烷、1-萘基锡烷、二苯基锡烷和三苯甲基锡烷作为良好的电子受体底物的反应中也很重要。
