While cruising the internet I came across this paper on using a polyoxymetalate to catalyse Fischer esterification. Unfortunately I have lost my library access so I cannot see the full
paper.
Polyoxymetalates were unknown to me, but an internet search gave lots of hits. It seems that they are catalysts useful for some oxidations.
The simplest polyoxymetalate might be the phosphomolybdate ion, which is OTC as a salt and is otherwise easy to synthesize, but I have no idea if it
has any catalytic properties.
Is anybody in a position to retrieve this paper?

Thanks. The paper uses phosphotungstic acid as the polyoxymetalate. This is OTC, and it can also be readily prepared from phosphoric acid and tungstic oxide.
