I spent a couple of hours typing up a document explaining substituents in organic chemistry, including the isoalkyls, neoalkyls, and various aromatic substituents. Saved it as a pdf and the computer ignored everything in the structures other than the R labels.

So every substituent is an R surrounded by white space.

Anybody have any thoughts on acesulfame potassium (artificial sweetener) as a source for acetoacetic acid? Looking at the structure, I'm hopeful both the enol ester and amide can be hydrolyzed in one step by boiling with NaOH.



Reflux condenser?? I barely know her!

INitroethane. Just a few ml, but I count it as a success.

Method 1 from this

*edit* pretty sure i would have had better yield if i had used a blender to mix the dry ingredients.

the sodium ethyl sulfate was where the learning curve kicked in, trust me. finally waited till my oil bath stabilized at 110C before i EVER set my flask/condenser/addition funnel in to it. temp in bath and internal flask both monitored (it gets warmer than this ya get diethyl either which is a side product for this procedure), slow dropwise addition of H2SO4 then reflux fer 'bout an hour. neutralized rxn mix with Na2CO3 until pH 7, suction filtered to remove the sodium sulfate (which i saved for use as dessicant), then evap'ed off the filtrate
