Formation and fac-mer isomerization of cationic phosphenium transition metal complexes formulated as (M=Cr, Mo, W) and (M=Mo, W)

In the reaction of (M=Cr, Mo, W) with under reflux with toluene or xylene, is prepared, which reacts with BF3*OEt2 to give, by OMe- abstraction from the phosphorus, a cationic phosphenium complex, .The facial isomer spontaneously isomerizes into its meridional form.The isomerization rate is in the order Cr > Mo > W. (M=Mo, W), which is prepared from and also reacts with BF3*OEt2 to give , whose fac-mer isomerization is slower than that of the corresponding bpy complex.
