1,4-Pentanediol as an Alternative Biomass-Derived Medium for the Phosphine-Free Heck Coupling Reactions.
Article in ChemSusChem, 2026. 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
The palladium-catalyzed Heck coupling represents a powerful method for constructing complex molecular structures, including biologically active ingredients. Implementing alternative reaction media in this industrially important transformation is crucial for developing environmentally safer processes and advancing sustainability. Herein, we report the first successful phosphine-free Heck protocol conducted in the biomass-derived solvent 1,4-pentanediol (1,4-PDO). The effects of key reaction parameters, i.e., Pd source, base type, and solvent water content, were systematically evaluated using iodobenzene and styrene as model substrates. Using the Pd(OAc)
