In this work, the interaction between compounds of chromium(VI) and organic bases, organic acids, amino acids and other compounds is reviewed. Whereas the reaction with organic bases led to the isolation of addition compounds, as well as chromates, dichromates and polychromates of chromium(VI), the reaction with organic acids, amino acids and peptides afforded chromium(VI) compounds, in addition to which the reduction of chromiun(VI) may also take place. Other compounds such as transition metal complexes, aminophosphonic esters and trimethylsulfoxide in their interactions with chromium(VI) compounds generate chromate and dichromate complexes. The compounds derived from organic bases present interest as effective and selective oxidants in organic chemistry. Moreover, together with those derived from organic acids, amino acids, and peptides are particularly important for the understanding of the mutagenic and carcinogenic process of chromium(VI) compounds.
