Utilizing bulky bidentate ligand systems with C2F5 and n-C3F7 groups, antiapicophilic arsoranes (5b and 5c, respectively) were synthesized. A kinetic study on the isomerization of these arsoranes to their more stable isomers showed that the barriers increased in the order of CF3 2F5 3F7 in accord with their steric bulk. It was also revealed that the degree of freezing isomerization was larger for the change from CF3 to C2F5 than from C2F 5 to n-C3F7, obvious from the differences in activation free energy at 363 K of 1.6 and 0.3 kcal mol-1, respectively. X-ray structural analysis of several precursors of these two systems disclosed the unique structures of these compounds.
