New catalyst, new reaction: The unprecedented cyanosilylation of nitroalkenes can be efficiently catalyzed by a bifunctional quinine derivative with tetraalkylammonium cyanide and thiourea moieties. The activation of the nitroalkene by hydrogen bonding to the thiourea, together with the presence of an “active” cyanide, provides a new mode of activation that leads to products in high yields and good
新的催化剂,新的反应:带有四烷基氰化铵和硫脲部分的双官能奎宁衍生物可以有效地催化硝基烯烃前所未有的氰基硅烷化反应。通过氢键合到硫脲上的硝基烯烃的活化,以及“活性”氰化物的存在,提供了一种新的活化方式,可导致高收率和良好的选择性(参见方案)。
