We have examined the effect of copper oxidation state in continuous gas phase coupled phenylacetylene hydrogenation (to styrene) with benzyl alcohol dehydrogenation benzaldehyde) over Cu/CeO2. Analysis by H2-TPR, XPS, XRD and STEM-EDX analyses demonstrates generation a range Cu states (Cu0 (13–77%), Cu+ (13–74%), Cu2+ (0–55%)). The stepwise formation styrene ethylbenzene was promoted stand-alon...

Recent investigations have shown the oxone-mediated oxidative methyl esterification of benzaldehyde derivatives using methanol. The reactions were accelerated in the presence of indium(III) triflate, a trivalent indium reagent, in many cases. Based on this method of methyl esterification of benzaldehyde derivatives, we further explored an application to heterocyclic aldehydes. The reactions wer...

A substituted anthraquinone (AQ), previously shown to photochemically generate benzaldehyde in methanol solution, was attached to a commercially available resin via an 11 carbon tether and an amide bond. Photolysis of the polymer-bound AQ with visible or 350 nm UV light resulted in the formation of benzaldehyde in yields of 50-55% as determined by HPLC. The phenolic positions in the polymer wer...

Functionalized indeno[1,2-b]chromene derivatives have been synthesized via condensation reaction of 1H-indene-1,3(2H)-dione with benzaldehyde and cyclization with 2-hydroxynaphthalene-1,4-dione in the presence of a catalytic amount of triethylamine (Et3N) in EtOH at room temperature. It was observed that benzaldehyde bearing electron donating group gave high yield of product, whereas, benzaldeh...

The 1:1 co-crystal N ′-[(2-methylphenyl)methylidene]pyridine-4-carbohydrazide–benzoic acid (1/1), C 13 H 11 3 O·C 7 6 O 2 , formed unexpectedly after autoxidation of benzaldehyde during the slow evaporation process a solution isoniazid in benzaldehyde. original intent synthesis was to modify with and crystallize product order improve efficacy against Mycobacteria species, but benzoic spontaneou...
