      Method to yield ketones     

An old reaktion to yield ketones is like this :

(R-COO)2Ca + (R´-COO)2Ca --> R-CO-R´ + CaCO3

Anyone tried this with Phenylaceticacid or MD-Phenylaceticacid ??

The source of this reaktion says that not all Carbonacidsalts will react and the yields are low.

If someone wants to try it i can also generate an attempt guidance but bees should know whats meant.

Thanks in advance.

      Temperature
(Rated as: good read)
    

You forgot to mention the temperature at which this reaction generally takes place, about 400°C, and the references Ber 3 198 (1870) & JCS 59 621 (1891) laugh See Post 358531 (moo: "P2P from phenylacetic acid and calcium acetate", Methods Discourse)Post 302647 (mysterious: "piperonal", Newbee Forum), Post 297386 (Elementary: "P2P from Acetone and Phenylacetic Acid", Chemistry Discourse), Post 256203 (WizardX: "Re: Propiophenone OTC route", Chemistry Discourse), Post 244672 (PrimoPyro: "Re: IS THIS THE BEST OTC P2P Route", Stimulants), Post 98406 (Torch: "R'CH2COCH3 via R'CH2COOH destructive distillation?", Chemistry Discourse) and Post 172207 (not existing) for previous in depth discussions wink The tube furnace method from Organic Synthesis and Vogel's is closely related, since they react the vapor of the two acids with a heated metallic carbonate catalyst smile

      UTFSE     

I should UTFSE.

Its possible ok.
As it is possible there are further questions. How differs the yield with other Metalions.
The first i would try to compare the yields of this reaktion with Ba, Sr, or Ca salts.  What is about other Katalysts? Ill try some katalysts i use every day but it would help if someone out there could help me. I have plenty of ideas about this reaktion which seems to be very interesting.

AC Allen et al. Differentiation of illicit phenyl-2-propanone synthesized from phenylacetic acid with acetic anhydride versus lead(II) acetate. J Forensic Sci 37(1) (1992) 301-322.

The illicit synthesis of phenyl-2-propanone (P2P) in clandestine drug laboratories from phenylacetic acid and acetic anhydride in the presence of sodium acetate or pyridine, or from the dry distillation of phenylacetic acid and lead (II) acetate is examined. These two routes are investigated using capillary gas chromatography (GC) combined with vapor-phase Fourier transform infrared (FTIR) spectroscopy and electron impact mass spectrometry (EIMS) detection (GC-FTIR-EIMS), and using nuclear magnetic resonance (NMR) spectroscopy to identify 21 reaction by-products. The mechanisms of the two reactions producing P2P are presented, along with the mechanisms giving rise to these by-products. This investigation has identified 4 reaction-specific compounds which can be used to differentiate the two synthetic methods.

      Limited Yields     

Yields are limited by the nature of the reaction, the mixed ketone is formed along with the two simple ketones, in the case of methyl benzyl ketone; dibenzyl ketone and dimethyl ketone are also formed crazy As has been pointed out before, the methylenedioxy ring is unlikely to survive such conditions, perhaps you should rethink your course of research, other routes have higher yields and less destructive conditions for such substituents wink

      Thats the reason why     

Thats the reason why i want to find a better katalysator for this reaktion.
The problem that also Dibenzylketone will form is soluted by using excess CH3Coo.  With the right katalyst this reaktion could be more mildly. Is it neccesary for this reaktion to be a solid-phase reaktion ?  Never say never.
Whats about generating  a  BaM(R-COO)2(R´-COO)2 or a M(R-COO)(R´-COO) intermediate in aprotic, anhydrous polar conditions ?? Or M(R-COO)(R´-COO)(Cl2) ? Ziegler Natter ?
