Preparation method of liquid crystal compound containing hesperidin-based methyleneoxy bridging group

The invention discloses a preparation method of a liquid crystal compound containing a myrac alcohol-based methyleneoxy bridging group. The liquid crystal compound has a general formula I which is described in the specification. The preparation method comprises the following steps of: (1) reducing myrac aldehyde into myrac alcohol; (2) reacting the myrac alcohol obtained in the step (1) with a sulfonylation reagent to prepare methoxysulfonate of the myrac alcohol; and (3) reacting the methoxysulfonate obtained in the step (2) with a phenol or alcohol compound with a general formula II to prepare the liquid crystal compound with the general formula I. The preparation method disclosed by the invention has the advantages of simplicity and convenience in operation, low pollution, low cost, few byproducts and the like, and is particularly suitable for industrial production.

Influence of the Ionic Liquid on the Activity of a Supported Ionic Liquid Phase FeII Pincer Catalyst for the Hydrogenation of Aldehydes

The catalytic hydrogenation of different aldehydes to the corresponding alcohols was investigated using an FeII hydride pincer complex as catalyst in the supported ionic liquid phase (SILP) reaction mode. Two different ionic liquids of the type [X4441][NTf2] with X=N or P were applied with mesoporous silica gel as support, which was coated first with a chemisorbed monolayer of the corresponding modified IL to remove acidic surface OH-groups and to prevent IL leaching. Quantitative conversion with turn-over frequencies in the order of 1000 h– 1 were obtained for various aromatic and heteroaromatic aldehydes and highly selective aldehyde reduction was observed also for substrates containing reducible C=C bonds. Aldehydes with longer aliphatic chains or cycloalkyl substituents, however, showed no conversion here, in contrast to a previous study with an imidazolium-based ionic liquid. These differences were ascribed primarily to differences in substrate/ionic liquid interactions. Whereas [N4441][NTf2] and [P4441][NTf2] gave essentially identical results for different substrates in single-batch reactions, prolonged use of the catalyst in repeated reaction cycles lead to a quick drop-off in catalyst activity in [P4441][NTf2], but a continuous, quantitative conversion in [N4441][NTf2].

Chemoselective Supported Ionic-Liquid-Phase (SILP) Aldehyde Hydrogenation Catalyzed by an Fe(II) PNP Pincer Complex

A base-tolerant supported ionic-liquid-phase (SILP) system containing a well-defined hydride Fe(II) PNP pincer complex has been prepared, structurally characterized, and used as catalyst in the hydrogenation of aldehydes to alcohols. The new SILP catalyst, with the optimum pore filling, was highly active exhibiting TONs and TOFs of up to 1000 and 4000 h-1, respectively, under mild conditions (25 °C, 10-50 bar H2 pressure) without significant leaching of both the complex and the IL.

Umpolung of protons from H2O: A metal-free chemoselective reduction of carbonyl compounds: Via B2pin2/H2O systems

H2O is routinely described as a proton donor, however, in the presence of diboron compounds, the umpolung reaction of H2O under metal-free conditions was successfully developed, which could afford hydride species, leading to a highly efficient and chemoselective reduction of CO bonds. This strategy exhibits excellent chemoselectivities toward carbonyl groups in the presence of ester, olefin, halogen, thioether, sulfonyl, cyano as well as heteroaromatic groups.
