标题:镍催化烯烃与 α-杂原子磷或硫烷基亲电试剂的对映聚合还原加氢烷基化反应
摘要:近年来,通过使用外消旋仲烷基亲电试剂与有机金属试剂的过渡金属催化交叉偶联反应,对映收敛 C(Sp3)-C(Sp3) 键形成反应取得了重大进展.在此,我们报告了与杂原子相邻的烷基-烷基键的不对称构建的一般过程,即镍催化的烯烃与 α-杂原子磷或硫烷基亲电试剂的对映聚合还原加氢烷基化反应.包括使用容易获得的烯烃,该反应具有相当大的优势,如反应条件温和,底物范围广,官能团兼容性好,使其成为传统亲电-亲核交叉偶联反应的理想替代方案.

摘要:A novel poly(arylene ether sulfone) having a sulfoalkoxy group, which has both of heat resistance and electroconductivity, is suitable as polymer electrolyte membranes used for high performance polymer electrolyte fuel cells, and does not use fluorine so that loads to the environment are small in the synthesis or disposal, a process of producing the same, and a polymer electrolyte membrane comprising the same. The poly(arylene ether sulfone) having a sulfoalkoxy group has a structural unit represented by the formula (1) mentioned hereinabove, and is produced by reacting a poly(arylene ether sulfone) having a hydroxyl group with a specific alkali metal compound and/or an organic base compound, followed by reacting with a specific sulfonating agent and then with a specific acid. A polymer electrolyte membrane is produced by film formation of the polymer.
