Amino-Supported Palladium Catalyst for Chemo- and Stereoselective Domino Reactions

A solid amino-supported palladium catalyst is used in an oxidative domino reaction for the diastereoselective construction of alkyne-substituted cyclopentenol compounds. This heterogeneous catalyst exhibits high efficiency and excellent chemoselectivity, as well as good recyclability. The chemoselectivity of the domino reactions was readily controlled by switching the solvent and catalyst. Asymmetric syntheses and an oxidative carbocyclization-borylation reaction have also been developed based on the heterogeneous palladium catalyst.

Method for preparing conjugated diyne compound by using copper complex

The invention relates to a method for preparing a conjugated diyne compound by using a copper complex. The method comprises the following step of: in the presence of alkali, carrying out a Glaser coupling reaction at room temperature by using alkyne as a raw material, the copper complex containing ortho-carborane Schiff base ligand as a catalyst and air as an oxidizing agent to prepare the conjugated diyne compound. Compared with the prior art, the copper complex containing the ortho-carborane Schiff base ligand is used for efficiently catalyzing the Glaser coupling reaction of alkyne to prepare the conjugated diyne compound; and the method has the advantages that selectivity is good, a catalyst dosage is low, reaction conditions are mild, a reaction can be performed in an open manner (wherein air is used as an oxidizing agent), a reaction rate is high, yield is relatively high, a substrate range is wide, and the method has wide application prospects in industry.

Strategy to isolate ionic gold sites on silica surface: Increasing their efficiency as catalyst for the formation of 1,3-diynes

A new strategy is presented to obtain an efficient heterogeneous gold catalyst constituted by isolated ionic gold sites, which is known to be effective in alkyne coupling reaction. The procedure is based on a significant difference between offered gold amount and available adsorbent sites on the support, ensuring the formation of very active isolated gold ion sites. In order to achieve this purpose, mesoporous silica xerogel was grafted with an ionic silsesquioxane containing charged ammonium quaternary group. The modified silica showed 0.25 mmol of cationic sites per gram of material and presented thermal stability up to 200 °C. This material was applied as support for immobilization of Au(III) ions as square planar AuCl4? complex. The gold amount offered was just 12 % of the exchangeable capacity. The catalyst was efficiently applied in the cross coupling reactions, in which only 0.22 mol% was applied to obtain symmetric and non-symmetric 1,3-diynes.
