ENERGETICS OF ORGANOMETALLIC SPECIES - THE ENTROPIC FACTOR

A rather simple procedure to estimate entropy changes of organometalli c reactions is described. It merely consists in finding organic or ino rganic reactions, for which the gas phase standard entropies are well known, that can mimic a given organometallic reaction. The merits and limitations of the method are discussed, and it is concluded that a ca reful use of model reactions can at least provide a reliable guideline to estimate or even to assess entropy data for many organometallic re actions.
