I am doing research on MMT (methylcycolpentadienyl manganese
tricarbonyl) which is the additive to gasoline in both leaded
and unleaded gasoline.  My question is this: a lot of research was
done in the 60's and 70's and everyone just seemed to know what the
decomposition products were and no one ever seems to say how they
found this out.  I would like a reference or even a hint about
when and how people decided that Mn3O4 was the primary decomposition
product of MMT.
please email me or post here
thank you
