    Résumé Organocatalyst trityl chloride (Ph3CCl), by in situ formation of trityl carbocation with inherent instability, efficiently promotes the cross-aldol condensation reaction between cycloalkanones and arylaldehydes in solvent-free and homogeneous media to afford α,α′-bis(arylidene)cycloalkanones in high yields. Moreover, an attractive and plausible mechanism based on observations and the literature is proposed for the reaction.

    Abstract The aim of this work is to introduce a novel and attractive protic acidic ionic liquid as catalyst for organic synthesis. To achieve this aim, N,N-diethyl-N-sulfoethanaminium hydrogen sulfate [Et3N-SO3H]HSO4} was prepared by reaction of NEt3 with ClSO3H and then with H2SO4. The novel acidic ionic liquid was identified by Fourier-transform infrared (FT-IR), 1H nuclear magnetic resonance (NMR)
    摘要 这项工作的目的是引入一种新颖且有吸引力的质子酸性离子液体作为有机合成的催化剂。为了实现该目的,通过使NEt 3与ClSO 3 H,然后与H 2 SO 4反应,制备了N,N-二乙基-N-磺基硫代硫酸氢铵[Et 3 N-SO 3 H] HSO 4 } 。通过傅立叶变换红外光谱(FT-IR),1 H核磁共振(NMR),13鉴定了新型酸性离子液体13 C NMR和质谱。然后在无溶剂条件下,在芳醛与环烷酮的交叉醇醛缩合反应中检测其催化活性,在短时间后以高收率得到α,α'-双(亚芳基)环烷酮。 图形概要

    The highly efficient and chemoselective α,α′-bis-substitution of alkanones is important in organic synthesis. Herein, a dimeric titanium cluster, Ti2Cl2(OPri)6·2HOPri (Ti2), is used in the Claisen–Schmidt condensation reaction, for the selectively activation of symmetrical ketones containing α,α′-methylene groups and production of α,α′-bis-substituted alkanones in high efficiency and chemoselectivity
    链烷酮的高效和化学选择性的α,α'-双取代在有机合成中很重要。在本文中,二聚物钛簇Ti 2 Cl 2(OPr i)6 ·2HOPr i(Ti 2)用于克莱森-施密特缩合反应,以选择性活化包含α,α'-亚甲基和高效和化学选择性生产α,α'-双取代链烷酮。高效和化学选择性可以扩展到各种典型的链烷酮和芳族醛。Ti 2的氧桥联二聚体基序 离子Ti-Cl键负责高效和化学选择性。
