Organic Derivatives of 0x0 Acids
Part I. Acids, Salts, and Esters of Group VIA Elements It seems ta be one of those simple cases which are so extremely difficult . . . Sir *lthurConan Statement of the Problem
Previous notes in this series have dealt with the classical inorganic 0x0 acids and their salts (11,and with some inorganic derivatives of these 0x0 acids structurally formed by the replacement of oxygen atoms andlor hydroxyl groups by peroxy groups, other chalcogen atoms, or halogen atoms (2).Besides these derivatives, there is a large group of derivatives of inoreanic 0x0 acids in which the central atom is bonded to one o r k o r e organic residues. These derivatives can be considered as being.formed hv the renlacement of hvdroxvl mouns of the inorgaiic oxo acid by organic residues. i n fact,
