Is there anyway for an amateur to get ahold of any these? Sadly, if I had to guess, I would say no :/
All of the "facile" syntheses I've come across require dangerous/expensive reagents.
Supposedly these are used in light curing epoxies, although probably obscure derivatives, and probably not in any useful quantities (although if you
can prove me wrong I would be very happy!).
I've posted here before on the subject I think, but I've been trying for quite some time to make my own photoresist formulation. A so-called "photo
acid generator" is a key component (which is what the diphenyliodonium salts serve as).
Thanks in advance!

Why don't you bother saying what country you are in? I have seen it for sale from a few sources in my country. It may or may not be economical to send
it to yours. Who knows! It's a mystery.

Oh sorry about that! I forgot that my profile doesn't list my location (it des now though!). I'm in Utah, United States.
I guess the only problem is that even if I could get a hold of it, the prices appear to be rather exorbitant (I'm still interested if you can manage
to get your hands on it though). Unfortunately, spinning on photoresist is really wasteful. It's somewhat hard to say how much I need since I doubt
I'd even get the formula correct on my first attempt. I'd probably want to make around 100 grams of resist. Even assuming I did get it right on my
first attempt, the cheapest I've seen it is like $80/5g, and considering that it needs to be added at ~4% by weight, that's roughly $64 per batch,
just for one component. Yikes!
