General bases and acids (B and BH)

Is there way to construct a general acid/base that would have lone pairs and/or a proton?  Maybe a B or BH with lone pairs so electron flow arrows could start on them or abstract H from them.

Hello Carl,

Do you mean sg like this?

 

(I have to admit that the rendering is not so nice and it is quite tricky to create.) I am also attaching the MRV file.

Best regards,

I was thinking something more along the lines of this.

 

You can do this with the edjucation example, but still not perfect: https://marvinjs-demo.chemaxon.com/latest/examples/example-lonepair.html

And still needs some tricks to find out the good attachment position.

Best regards,

Efi
