Synthesis, structural elucidation, and stereochemistry of five-coordinate organoarsenic catecholates
The synthesis of five-coordinate organoarsenic catecholates, with substitution of 3-CH/sub 3/, 4-CH/sub 3/OC(==O); 4,5-C/sub 6/H/sub 4/, and 3,3'-C(==O)NH(CH/sub 2/)/sub 4/NHC(==O) groups on the catechol ring and CH/sub 3/ or Ph (phenyl) on arsenic, was performed. These reactions provided new insight into the structures and stereochemistry of these organoarsenic compounds. In one case, 3-methylcatecholate of phenylarsonic acid, a single-crystal x-ray analysis provided unequivocal evidence for cis stersochemistry of the methyl groups on the catechol rings, an essentially rectangular-pyramidal configuration around arsenic, and a preferred conformation of the phenyl group in relation to the oxygens surrounding the arsenic atom.
