    Notes: Macrocyclic Arsinous Acid Ester. IVThe three-valent arsenic atom is a Lewis-acid, which formes inter- or intramolecular adducts. The reaction with aminoalcoholes and diols, described in this paper, leads to the formation of cyclic and non-cyclic arsinous acid esters (3, 5, 6, 7, 9, 10, 12, 13, 15, 16, 18), some of them containing a N→As-donor-bond.
