 Title    Chemie polyfunktioneller Liganden, 53 [1] Über methyl-substituierte Triarsa-trioxa-, Triarsa-trithia- und Triarsa-triaza-adamantane und über den stark aufgeweiteten Adamantan-Käfig im Schwefel-Derivat Chemistry of Polyfunctional Ligands, 53 [1] About Methyl-substituted Triarsa-trioxa-, Triarsa-trithia-and Triarsa-triaza-adamantanes and about the Strongly Spread Adamantane Cage in the Sulfur Derivative  
 Abstract    The reaction of l,l,l-tris(diiodarsinomethyl)ethane, CH3C(CH2Asl2)3 (1), with H2O, H2S and CH3NH2 in THF gives the adamantane cage compounds CH3C(CH2ASO)3 (4), CH3C(CH2ASS)3 (5) and CH3C(CH2ASNCH3)3 (6) in high yields. The crystal structure of 5 has been determinated by X-ray diffraction. The unit cell (space group P2i/w) contains 4 isolated molecules in a cubic closest packing. The heteroadamantane 5 has an enlarged cage structure with extremely spread C-C(H2)-As bond angles of 124° at the methylene carbon atoms. Some pharmacological properties of the adamantane derivatives 4 and 5 have been studied. All compounds have been characterized by mass spectrometry and infrared, Raman and X H NMR spectroscopy.
