File:NegishiScheme1.png

Replaced in ko:네기시 반응 with TeX equivalent:

${\begin{matrix}{}\\{\color {Red}{\ce {R}}}{-}{\color {Blue}{\ce {X}}}+{\color {Green}{\ce {R}}'}{-}{\ce {Zn}}{\color {Magenta}{\ce {X}}'}\ {\ce {->[{\ce {PdL}}_{n}{\text{ or }}{\ce {NiL}}_{n}]}}\ {\color {Red}{\ce {R}}}{-}{\color {Green}{\ce {R}}'}\end{matrix}}$

•  Keep TeX gives font that is often not MOS-standard for chemical diagrams and therefore mismatched (poor display effect) vs more-complex images. I have therefore placed this image back in use in en:Negishi coupling. DMacks (talk) 20:04, 30 January 2021 (UTC)

I have to agree with you in parts. Unfortunately, I used someone else's formula made in 2016 instead of making my own. Therefore, I did not notice that the font and characters for the charge were different from the original representation. Please excuse this carelessness and thank you for your important hint. I have improved both aspects.

${\begin{matrix}{}\\{\color {Red}{\mathsf {R}}}{-}{\color {Blue}{\mathsf {X}}}+{\color {Green}{\mathsf {R'}}}{-}{\mathsf {Zn}}{\color {Magenta}{\mathsf {X'}}}\ {\ce {->[{\mathsf {{PdL}_{n}}}{\text{ or }}{\mathsf {{NiL}_{n}}}]}}\ {\color {Red}{\mathsf {R}}}{-}{\color {Green}{\mathsf {R'}}}\end{matrix}}$

By the way, I don't think it's fair to include the image in the article en:Negishi coupling (which I haven't edited) while this discussion is still ongoing. --W_I^KImaniac 10:15, 31 January 2021 (UTC)

The subscript "n" were not legible in the first (italics is reasonable but not required...would have to check a style guide to see if either is actually preferred). Actually in general the text above/below arrows in TeX renders in a pixelated or JPEG-artifact-like way. Perhaps there is a general fix for this? Those areas look to be a slightly smaller font-size, whereas chemistry images typically have the same font/size/etc on the arrow vs left/right of the arrow:

${\mathsf {Reactant}}{\ce {->[{\mathsf {Cat./solv.}}]}}{\mathsf {Product}}$

That is "Cat./solv." should match "Reactant". More importantly, that the top of the capital "C" of "Cat" is cropped. (screenshot). Until the TeX is "at least as good as" the plain graphics in terms of how the page displays, I'm making an editorial decision to use the better among the options there (I think the image had been in use until it was replaced; I undid that change).

•  Keep In my opinion, we should keep both the PNG file as well as the TeX code for different uses. Chem Sim 2001 (talk) 09:45, 20 February 2021 (UTC)
