Copper(II) acetate, cas is 142-71-2,the copper-catalyst compound, it is a common compound, a new synthetic route is introduced below.

Copper tetraphenyl porphyrin was synthesised by taking tetra phenyl porphyrin[H2(TPP)]16(500mg) in chloroform(100ml).Copper(II) acetate(200mg) in glacial aceticacid(50ml) was added to the above solution andthe mixture was refluxed for 2hrs. The contents wereconcentrated to a volume of about 50-60ml andcooled to room temperature which resulted in crudecopper-tetraphenyl porphyrin Cu(TPP) (about450mg). The crude product was purified by columnchromatography using neutral alumina andchloroform as eluent. On elution the unreactedtetraphenyl porphyrin was eluted out first, followedby pure Cu(TPP). The chloroform fraction containingCu(TPP) was concentrated to obtain pure crystalsof Cu(TPP)[2]. The formation of Cu(TPP) wasmonitored by UV-visible spectroscopy which givepeaks-around 580, 541 and 417nm respectivelyconfirming the formation of Cu(TPP) (yield=400mg).
