  借氰反应：镍催化的氰醇和醛/酮直接转化为 β-氰基酮†

  摘要：

  通过前所未有的“借氰反应” ，氰醇与醛或酮的直接镍催化、高原子和多步经济的反应已被开发出来。氰醇的 C-CN 键断裂，然后是羟醛缩合和氰化物与 α,β-不饱和酮的共轭加成，以良好至高产率提供一系列外消旋 β-氰基酮。使用商业和毒性较低的 CN 源的实际程序预示着该协议的广泛应用。

  日期：2022.6.3

  Electrocatalytic three-component acylcyanation and aminocyanation of simple alkenes have been developed. The protocol features high functional group tolerance and can easily be scaled up. The key to success is to use an electrophilic cyanation source, enabling a broadened use of alkenes to aliphatic ones for acylcyanation.

• An efficient conjugate hydrocyanation of chalcones and related enones with TMSCN under solvent- and additive-free microwave conditions
  作者：Hirokazu Iida、Tatsuya Moromizato、Hiroshi Hamana、Kiyoshi Matsumoto

  日期：2007.3

  A first example of solvent- and additive-free 1,4-addition reaction of alpha,beta-unsaturated ketones such as chalcones, 3-nonen-2-one and benzalacetone with trimethylsilyl cyanide (TMSCN) is described. The addition of TMSCN to chalcones, 3-nonen-2-one, and benzalacetone under microwave irradiation in the absence of Lewis or Bronsted acids and solvents, yielded the corresponding beta-cyanoketones in good to moderate yields, as quite rapidly as in 5 min. No systematic substituent effect of chalcones on the yields was observed. No reaction of alpha,beta-unsaturated esters such as methyl cinnamate with TMSCN took place under the same conditions.

• Thiourea-functionalized magnetic hydroxyapatite as a recyclable inorganic–organic hybrid nanocatalyst for conjugate hydrocyanation of chalcones with TMSCN

  The recoverable nanomagnetic catalyst was manufactured based on thiourea modified magnetic hydroxyapatite. Magnetic hydroxyapatite (mHAp) as the inorganic-organic hybrid support was fabricated using co-precipitate condition and then modified via the covalently anchoring of 1-(3,5-bis(trifluoromethyl)phenyl-3-propyl)thiourea. The hybrid nano-catalyst has been identified by TEM, SEM, FTIR, BET, TGA, and XRD. This nanocatalyst appeared efficient and robust in the 1,4-addition reaction of TMSCN to alpha,beta-unsaturated aromatic enones in excellent yields (85-96%) under mild reaction condition and simple work-up process. This recoverable organocatalyst has a great potential as an industrially viable and eco-safe catalyst. (C) 2015 Elsevier B.V. All rights reserved.
