Can anyone tell me the procedures for synthesis of metal acetylacetonates and diethyldithiocarbomates?.. For Nano particles synthesis purpose...
I would direct you to SciFinder Scholar or ISI Web of Science (Science Citation index). With many transition metals, these are well traveled syntheses. Another place to look would be the series Inorganic Syntheses. You may need to look back into the 1960-1990 for some of the papers, though. A good science librarian should be able to help you ferret some of these out, too, if you are not coming up with productive searches.
Dear D. Babu Sir..
Synthesis of metal acetylacetonates can be done by adding required amount of acetyl acetone to a hot solution of your metal precursor in the desired solvent. This method works prefect for the synthesis of vanadium acetylacetonate from V2O5 or VOSO4.
Vanadium pentoxide is taken in required amount of ethanol and acidic aqueous solution. This solution is refluxed with stirring. With time V2O5 gradually dissolves and in about 2-3 hrs the solution becomes green in colour and then suddenly turns into blue. This is nothing but Vanadium in +4 state. The hot solution is filtered to remove any undissolved or unreacted V2O5. To the clean filtrate, added a fresh solution of acetyl acetone (2 equivalents). Green precipitate of Vanadyl acetylacetonate separates out on neutralization of the solution with saturated sodium carbonate solution. Solution is filtered to get the crude product. Upon recrystallisation with chloroform, we can get the pure bluish green crystals of vanadyl acetylacetonate.

Thank You.. Prof. Neil Law and Ms. Manasa for your suggestions and ideas.. Thanks..
