摘要
在钯及相转移催化剂存在下，烯基硒化物与氰化钾在苯中可顺利发生交叉偶联反应，提供了α，β－不饱和腈的立体选择合成法，产率达７５％～９５％。
In the presence of Pd(PPh 3) 4 and 18 crown 6,alkenyl selenides can undergo easily cross coupling reaction with potassium cyanide, offering a convenient method for the stereoselective synthesis of α,β unsaturated nitriles with a yield of 75%￣95%.
