FISSION OF AS-AS BONDS IN ELEMENTAL ARSENIC BY ALKALI METALS IN LIQUID AMMONIA. A ROUTE TO MONOALKYL ARSINES

FISSION OF AS-AS BONDS IN ELEMENTAL ARSENIC BY ALKALI METALS IN LIQUID AMMONIA. A ROUTE TO MONOALKYL ARSINES

Addition of two mol equivalents of t-butyl alcohol to a mixture of powdered arsenic and three mol equivalents of lithium in liquid ammonia gives a suspension of lithium arsenide LiAsH 2 . Subsequent addition of a large excess of t-butyl alcohol and n-octyl iodide at very low temperatures affords n-o...

Zusammenfassung:Addition of two mol equivalents of t-butyl alcohol to a mixture of powdered arsenic and three mol equivalents of lithium in liquid ammonia gives a suspension of lithium arsenide LiAsH 2 . Subsequent addition of a large excess of t-butyl alcohol and n-octyl iodide at very low temperatures affords n-octyl arsine in -65% yield.
