Abstract
[reaction: see text] The Heck reaction of aryl chlorides was investigated in the presence of defined monocarbenepalladium(0) complexes. Activated and nonactivated aryl chlorides provide the corresponding cinnamic esters and stilbenes in (n)Bu(4)NBr as a ionic liquid in good to excellent yields.
摘要
[反应：见正文] 在特定的单卡宾钯（0）配合物存在下研究了芳基氯的Heck反应。在离子液体（正丁基）4NBr中，活化和未活化的芳基氯均能以良好至优异的产率提供相应的肉桂酸酯和二苯乙烯。
