The title mol-ecule, C(26)H(22)N(4)S, is composed of three main parts, viz. a triphenyl-amine group is connected to a phenyl ring by a thio-semicarbazone moiety. The C= N double bond has an E conformation. The crystal packing is dominated by strong hydrogen bonds through the thio-semicarbazone moiety, with pairs of N-H⋯S hydrogen bonds linking the mol-ecules to form inversion dimers with an R(2...

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...
