Anthracene
What would be the easiest achieveable route to make Anthracene for a noob with very litle experience in C never mind OC ?
I have tried the 'Partially combusted Organic Material route', however that is very messy, yet yeilded a partial result.
The wiki says things i simply do not understand yet, i.e. 'cyclodehydration of o-methyl- or o-methylene-substituted diarylketones '
This is my 2^8 th post. Digitally significant for those with two fingers.

What the wikipedia is saying is essentially this. The type of reaction is a 'cyclodehydration'. So likely one can imply that there will be a loss of
water{dehydration} (an H2O will leave the molecule), and will form a cycle{carbon chain that closes in on itself}. The o-methyl diarylketone is a type
of compound I guess you could say. The O- or P- or M- is IUPAC short-hand for Ortho, Meta, and Para regiosomers (http://en.wikipedia.org/wiki/Arene_substitution_pattern). This pertains typically but not neccesarily exclusively to benzene derivative. A ketone
is a common functional group but in this case what I believe you are looking for is two benzenes bridged by a formaldehyde type functionality. My
chemical drawing program says the name of this compound is, (2-methylphenyl)(phenyl)methanone.
A great website for looking up structures is - http://www.chemicalize.org/structure/#!mol=%282-methylphenyl... really helped me when learning things.
The common name for this reaction is apparently the "elbs reaction" (http://en.wikipedia.org/wiki/Elbs_reaction) . Looks like an old timey reference, K. Elbs, E. Larsen: Ueber Paraxylylphenylketon, in: Ber. Dtsch.
Chem. Ges. 1884, 17, 2847–2849; doi:10.1002/cber.188401702247. Making anthracene though hmm, without that starting material, could be pretty tricky.
There certainly are ways to get to that starting material though. It would take a few reactions, at least one depending on what you have available.
What are you looking to do? Do you specifically want anthracene and want to go on a synthetic adventure? Are you equipped enough to do a grignard
reaction safely? Or is this a whole new world for you?

I'm interested in Anthracence as it i an organic semiconductor, and it'd be fun to see what can be done with it.
OC is a whole new world entirely to me.
Although i may well be physically equipped to do grignard reaction, not knowing what a grignard reaction Is would be a serious drawback.

I think you'd be better off buying anthracene, it's not impossible to come by. Leaping into advanced organic syntheses without any previous knowledge
is a bad idea. You could always get back to it after doing organic chemistry for a while.

Agreed.
Making it is way beyond what i can do.
I will buy some as suggested.

I definitely think you should buy some for now. However, I would be lying if I didn't say that it could be very fun and rewarding to try and make some
yourself later down the road as a project.
Kind of like the polarimeter I am working on. I knew next to nothing about electronics before starting it. Set a goal did an appropriate amount of
research, experimented now I am starting development. You can self-teach chemistry, but there are danger's/hazards, theory, and techniques which must
be learned prior to attempting to do so. Either way best wishes.

'Man's gotta know his limitations' says Clint Eastwood in some film or other.
Yes, i would be fascinated, excited, and maybe dead tinkering with totally unknowns.
At my level of understanding, it would be Science Madness to attempt it
