A while back, I had a teacher that gave us organic chemistry reaction summaries e.g. suppose the topic was benzene, the summary looked like this:
I was wondering if this would be possible to replicate in LaTeX. I've started looking into chemfig, but is there any convenient way to make a "circle" of reaction like this? i.e. with automatic even spacing, putting reaction conditions on the arrows etc,
Thanks!
the subtitles are for you to put.

with alignment of the centers of the rings
