The result shows that, under this catalytic reaction, the Heck arylation of iodobenzene with acrylic acid has a good stereoselectivity and only trans-cinnamicacid is produced.
结果表明，在此催化剂作用下，碘代苯与丙烯酸反应具有较好的立体选择性，只生成反式苯丙烯酸；

The biotransformation of trans-cinnamicacid to L-phenylalanine by using phenylalanine ammonia-lyase (PAL) has, therefore, become very important in the research and development of this field.
