The red boxed ones are cis and trans isomers of the enol.
Before anyone comments. I know that enols are in equilibrium with the keto form, the latter favoured.
But these are still isomers with that molecular formula.

No, they are different, but the 3-chlorooxetanes are the same. I also have 2-chlorovinyl methyl ether (E and Z), 1-chlorovinyl methyl ether; and 3-chloropropanal, E and Z but-1-ene hypochlorite and but-2-ene hypochlorite, making 25

[curiouscat]

What about these? Valid?

Damm, forgot the methyl ethers etc. Thanks.
Must have boggled my eyes and brain cell.

The last two are the methyl ethers I mention, hadn't got as far as the chloromethyl vinyl ether you draw first.

Damm, forgot the methyl ethers etc. Thanks.

And these?



....and more (or am I violating any valency rules? ).

Of these, the chloropropanal has been listed. Can someone consolidate all the structures to date I think we are wasting a bit of time crossposting etc.

[discodermolide]

I'll try and put it all together. Give me some time.

Listed but not drawn. 

My bad. I'm too dumb to convert names to structures.

[discodermolide]

Up to now I have 30, with everyone's suggestions. I'll wait and see if any more come in before I post the structures.

Everyone above has forgotten the organic hypochlorites.(edit: oops, missed sjb's post) R-O-Cl  well known but stinky.  I made ethyl hypochlorite once back in the day.

Also R-Cl(+)-O(-) (organic chlorites) could be considered, but I am away from scifinder and can not even confirm the existence of this type of compound. 

So that should add a pile more isomers

[discodermolide]

I think sjb mentioned them, thanks. I'll have another look for my compilation.

Sorry, this should be prop-1/2-enes for the hypochlorites. Can these be both O- and Cl- bonded to the carbon chain?

Post them (please ); otherwise it is hard to know which ones haven't been included.
