  Regioselective Addition of Various Heteronucleophiles to (Styrene)Cr(CO)₃ Complexes

  摘要：

  (Styrene)Cr(CO)(3) complexes underwent the addition of various heteronucleophiles such as alcohols, amines, and thiols, in the presence of KOH, and the beta-addition products were selectively obtained in moderate to excellent yields. The structural details and features of the product complexes were also elucidated.

  Palladium catalysed cross-coupling of (fluoroarene)tricarbonylchromium(0) complexes

  摘要：

  氟苯三羰基铬(0)配合物被发现可进行Suzuki和Stille交叉偶联反应，分别生成功能化联苯和苯乙烯配合物，产率最高可达87%和52%。Suzuki反应在二甲氧基乙烷中以三(二亚苄基丙酮)二钯-三甲基膦-碳酸铯为催化剂并回流时效果最佳。Stille反应在二甲氧基乙烷中以三(二亚苄基丙酮)二钯-三甲基膦-氟化铯为催化剂并回流时效果最佳，且这两种反应均不受配合物苯环上的甲氧基影响。Suzuki反应能容忍芳基硼酸环上的氯基，但不能容忍溴基。

  (Fluoroarene)tricarbonylchromium(0) complexes were found to undergo Suzuki and Stille cross-coupling reactions to form functionalised biaryl and styrene complexes in up to 87 and 52% yields, respectively. The Suzuki reactions were optimal with dipalladium tris(dibenzylideneacetone)–trimethylphosphine–caesium carbonate in DME at reflux. The Stille reactions were optimal with dipalladium tris(dibenzylideneacetone)–trimethylphosphine–caesium fluoride in DME at reflux and neither was adversely affected by a methoxy group on the complexed ring. The Suzuki reaction tolerated a chloro group on the arylboronic acid ring but not a bromo group.
