silylated primary amines was achieved by combination of 1,1,3,3-tetramethyldisiloxane (TMDS) as the hydrosilane and a catalytic amount of Co(OPiv)2 (Piv = COtBu) associated with isocyanide ligands. The resulting silylated amines were subjected to acid hydrolysis or treatment with acid chlorides to give the corresponding primary amines or imides in good yields. One-pot synthesis of primary amides to
通过将1,1,3,3-四甲基二硅氧烷(TMDS)作为氢化硅烷和催化量的与异氰配体缔合的Co(OPiv)2(Piv = CO t Bu)的组合,可以将腈还原为甲硅烷基化的伯胺。将所得的甲硅烷基化的胺进行酸水解或用酰氯处理,以高收率得到相应的伯胺或酰亚胺。铁-钴双催化剂体系也可以通过氢化硅烷将伯酰胺一锅合成伯胺。
