Vanadium lends itself also to iodometric method of determination. The vanadate solution is reduced with hydrobromic acid, excess of potassium iodide is added, and the iodine thereupon liberated is estimated with sodium thiosulpliate solution. The reaction is 3... 

Analogous to the preceding cw-dioxovanadium(V)-catalyzed system of bromide oxidation by dihydrogen peroxide, Secco carried out a detailed kinetic analysis of vanadate-catalyzed oxidation of iodide by dihydrogen peroxide [75], Peroxovanadate species (i.e., V0[02]+ and V0[02]2 ) or their hydronated forms oxidize iodide in acidic aqueous solution, forming V02+ and V0(02)+, respectively however, once V0(02)+ and V0(02)2 are consumed, iodide reduces... 

Reduction of 2-unsubstituted 1,3-dithiolylium salts, e.g., 389 (R = H), with zinc or hexacarbonyl-vanadate leads to dimerization affording 390 the reduction of 2-methylthio-dithiolylium iodide 389 (R = SMe) with zinc in the presence of bromine, however, gives TTF 391.
