Lead:

It doesn't seem like a new lead was added? The original lead, however, was very good, so I think this is okay.

Content:

Content added is very informative! I enjoyed reading about the history of the Ullmann reaction, as well as how it was developed. I think adding more section headings could be useful: the section added seems like a history section, but the current article does not have a history section.Tone and Balance:

Tone is neutral and not biased towards any side!

Sources and References:

Might be good to add a few more references, especially since they're discussing a very chemical topic. I think the history section would benefit a lot from additional references, as well as the explanation of the mechanism! As well, the addition of internal links to other wikipedia pages could be useful.

Images and Media:

No images or media is added, but the original page has quite a few images so this is okay!

Overall Impressions:

Could be good to title different the sections with subtitles to emphasize separation! For example, Current State can be a subheading of History and Development. As well, adding a diagram of the mechanism could be very helpful rather than just explaining it in words. I think the history context of this reaction is very interesting, and I'm glad it was added!
