Structure of 2,5-difurfuylidenecyclopentanone?

Yes, I don't want to type that name in again, so I'll refer to it as DFC.

Okay, I haven't a clue. Mainly because I have no idea what "idene" means. Is it simply furfurylidene, as in, furfuryl, with a double bond somewhere?

We took some cyclopentanone, added some NaOH, and added some furfural. The product we are supposed to get is DFC. This is a Claisen-Schmidt condensation reaction, if that helps. I can't find a structure anywhere online, so here I am. And I thank you.

there, i used chemdraw:

Thanks for that. I've been trying to find chemdraw on kazaa with no luck, but surely it will turn up one day. How did you get your copy?

I am now interested in finding the name of a structure, and I'm guessing chemdraw would again help me greatly here. However, as I mentioned above, I can't find it on Kazaa right now, and this is due by thursday, so I'm in quite a pickle.

So, would you mind putting this into your program and give me the name? I need to know the melting point and without the name...yeah.

Anyways, it's a fluorene molecule, on the cyclopentane part, at the bottom (the vertex, the V) is attached a double bond to a carbon, and this carbon is attached to a benzene ring.

I hope that was clear enough.

>=-(benzene)

to give you some kind of idea. THe > is the vertex of the cyclopentane (which is part of the fluorene), the = is the double bond, and the - is a single bond to the benzene.

THanks a bunch!

Use chemsketch, search google for it...
