父母3月1号以后要去上海签证,
上海领事馆网页上这个地方说
“自2010年3月1日起,所有在中华人民共和国境内申请美国非移民签证的申请人都需填
写在线非移民签证申请表(即“DS-160”表)。”
http://shanghai-ch.usembassy-china.org.cn/new_online_application_.html
然后继续看了看具体的信息,这个地方又说“此表仅适用于申请人在已经实施这种新电
子表格和审理程序的美国大使馆或领馆使用”
http://shanghai-ch.usembassy-china.org.cn/asked-questions.html#1
然后查到list里面只有中国沈阳。
有点confused的地方是,是3月1号中国所有美国领事馆都要用DS160,还是只有在沈阳
签要DS160啊?
谢谢

主要贡献是?
1.用COOK 作为Directing group? 已经在他的很多jacs中说明过。
2.Acrylate用于C-H 活化也不算很NEW(Leeuwen,JACS, 2002,1586.)
3.Ligand 控制选择性?其实也就是比用位阻好了一些.
觉得发SCIENCE有点过头,JACS没有问题.

其实这篇总体还是不错的,ligand提高活性和区域选择性,这在以前还是很难的!
赞一下!
