This file illustrates the synthesis that Kealy and Pauson attempted for w:fulvalene that actually produced w:ferrocene. It was originally reported in Nature in 1951 (doi:10.1038/1681039b0) and is discussed in Pauson's 2001 retrospective on ferrocene in w:J. Organomet. Chem. (doi:10.1016/S0022-328X(01)01126-3). It is derived from the existing File:Kealy_Ferrocen_Synthese.svg uploaded in 2001 by Bert.Kilanowski and EdChem's alterntive File:Kealy and Pauson synthesis of ferrocene.jpg uploaded on 8 April 2019. It has been adapted by EdChem on 11 April 2019 from the version uploaded a few days before using Microsoft Paint, saved as a .jpg file, and uploaded for part of a discussion at w:Wikipedia talk:WikiProject Chemistry initiated by EdChem with this edit and this is the state of the discussion at the time of this upload.

The Bert.Kilanowski source file is stored on Wikimedia Commons with a w:Creative Commons CC0 1.0 Universal Public Domain Dedication license. Both the upload on 8 March 2019 and this file are being listed with a PD-Chem notice as it is in the public domain as simple chemical structures and equations and thus ineligible for copyright protections.

This image of a simple structural formula is ineligible for copyright and therefore in the public domain, because it consists entirely of information that is common property and contains no original authorship.

This chemical image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Kealy and Pauson synthesis of ferrocene v2.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

This chemical image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
