Synthesis of arylarsenic acid by interaction of aryldiazo compounds in the presence of catalysts and arsenite salts.

Schmidt H. modification - in neutral medium and without catalysts.

Starkey modification - using diazo boronfluorides which are more stable to decomposition and creation of secondary products.

Bart-Schmidt H. variant - using antimony chloride instead of arsenite to produce arylantimonious acid.
