Benzhydryl compounds

The benzhydryl compounds are a group of organic compounds whose parent structures include diphenylmethane (which is two benzene rings connected by a single methane), with any number of attached substituents, including bridges. This group typically excludes compounds in which either benzene is fused to another ring (bicyclic, tricyclic, polycyclic)[1] or includes a heteroatom, or where the methane connects to three or four benzenes.

Heteroaromatic

These species are not strictly benzhydryl-containing but are analogous.

gollark: Actually, only the last 90 lines are the incomprehensible image generation code.
gollark: Is this... generating the positions of a square "ring" around a point?
gollark: I mean, what?
gollark: ```haskellringAt :: Position -> Int -> [Position]ringAt (x, y) l = sides ++ top ++ bottom where top = [(n + x, l + y) | n <- [-l .. l]] bottom = [(n + x, -l + y) | n <- [-l .. l]] sides = concat [[(l + x, n + y), (-l + x, n + y)] | n <- [1 - l .. l - 1]]```
gollark: But yes, you may be right, I have no idea of what some of this does.
