The dehydration reactions from primary amides to nitriles were catalyzed by the [CNC]-pincer hydrido cobalt(III) complexes [(ortho-F4C6CHNC10H6)Co(III)(H)(PMe3)2] (1), [(2,5-F2C6H2CHNC10H6)Co(III)(H)(PMe3)2] (2) and [(2,4,5-F3C6HCHNC10H6)Co(III)(H)(PMe3)2] (3) as catalysts with (EtO)3SiH as an efficient reducing agent. These hydrido cobalt(III) complexes as catalysts are suitable for many substrates and have good functional group tolerance. Among the three cobalt hydrides, complex 2 is the best catalyst. This is the first hydrido cobalt complex-catalyzed dehydration of primary amides to nitriles.

[CNC]-夹子氢化钴(III)配合物催化伯酰胺脱水成腈
[CNC]-夹子氢化钴(III)配合物[(邻-F 4 C 6 CH N C 10 H 6)Co(III)(H)(PMe 3)2催化从伯酰胺到腈的脱水反应](1),[(2,5-F 2 C 6 H 2 CH N C 10 H 6)Co(III)(H)(PMe 3)2 ](2)和[(2,4,5-F 3 C 6 H CH N C 10 H 6)Co(III)(H)(PMe 3)2 ](3)作为催化剂,并以(EtO)3 SiH作为有效的还原剂。这些氢化钴(III)配合物作为催化剂适用于许多底物,并具有良好的官能团耐受性。在三种氢化钴中,配合物2是最好的催化剂。这是第一个氢化钴钴配合物催化的伯酰胺脱水成腈。
