Efficient Formylation of Alcohols Using a Core-Shell Magnetic Nanocomposite
Article in Current organic synthesis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThe protection of the hydroxyl group as formamides is a crucial initial step in pharmaceutical synthesis.
methodsIn this study, we investigated the O-formylation of alcohols using dimethylformamide (DMF) in a mixture with a new magnetic nanocomposite Fe
resultsThe results demonstrate that this core-shell heterogeneous nanocomposite facilitates the formation of alkylformate, yielding products with high efficiency ranging from 79% to 96% within a remarkably short reaction time of 1 to 12 hours at room temperature, depending on the substrate structure. Significantly, the presence of this nanocomposite exhibits remarkable selectivity, favoring the formylation of less hindered benzylic and aliphatic primary alcohols. However, bulkier alcohols and phenols exhibit lower reactivity under these conditions and thiols do not react. The simplicity of the work-up procedure, combined with the magnetic recyclability, makes it reusable and environmentally friendly.
conclusionThis study highlights the efficacy of this novel magnetic nanocomposite in facilitating formylation reactions, emphasizing its potential for application in pharmaceutical synthesis and bio compounds. This is due to its attributes of non-toxic nature, stability, and significant advantages over conventional methodologies.
