Does anyone have a clue of where the Bio & Twodogs bees from the old times went ? Would be interested to have a bit a talk with these artists ^^

I know what happened to both of them but please don't ask questions such as this on our forum ever again. If they wanted you to know they would be here under name if possible.

I said it before, H2SO4 ,Sodium Bisulfate as well as HCl was known to catalyze the aldol... What happens when you drip H2SO4 into NaCl? Think about it fellows or keep on gassing for hours and hours when a slow drip could suffice.
There once were some bees and you took all there stuff!
You pissed off the wasp now enough is enough!!!

Cheers to them then.

As most BV procedures form the unsaturated ketones are quite low yielding and not so specific when no lewis acid is used, I was wondering about alternatives.

Twodogs was indeed talking about two other ways from the butenone to the ketone. One of them was the oxidation of the unsaturated ketone using NaOCl to a cinnamic acid and then decarboxylation to the ketone. Does anyone have a reference for this ?
