Substituted phenylarsonic acids; structures and spectroscopy

Full NMR and ESI-MS spectra, and differential scanning calorimeter data are presented for 15 substituted phenylarsonic acids, including two new fluoro-substituted examples. X-ray crystal structure determinations of five examples (phenylarsonic acid and the 4-fluoro-, 4-fluoro-3-nitro-, 3-amino-4-hydroxy- and 3-amino-4-methoxy-substituted derivatives) were determined and the H-bonding crystal-packing patterns analysed.

SYNTHESIS AND PROPERTIES OF ARYLARSONIC ACIDS

1.A number of arylarsonic acids with various substituents in the ortho, meta, and para positions in the benzene ring were synthesized from diazonium salts by the Bart reaction; the products were characterized by their IR spectra. 2.By the DTA method it was established that arylarsonic acid molecules were linked together through hydrogen bonds to form oligomeric associated forms. 3.The IR spectra of arylarsonic acids confirm the presence in them of strong hydrogen bonds through which they are able to undergo association into two forms differing in the symmetry of the d isposition of the As=O bonds.A form which gives a C band arises if the arsonyl oxygen participates in the formation of two hydrogen bonds simultaneously, as a result of which the molecules are linked together to form endless chains and columns.In the other form there are probably cyclic dimers with intermolecular H bonds.
