- Synthesis and crystal structure of 1,2-Di-t-butyl-1,2-diiododiarsane (t-C4H9AsI)2 and synthesis of 1,2,3,4-Tetrakis(t-butyl)tetraarsetane (t-C4H9As)4 via selective reduction of t-Butylarsenic Diiodide t-C4H9AsI2
-
1,2,3,4-Tetrakis(t-butyl)tetraarsetane (t-C4H9As)4(4) has been synthesized by reduction of t-butylarsenic (III) diiodide (1) with equivalent quantities of either Mg, Ca, Zn, Li, or CoCp2 in THF at low temperatures in high yields. Treatment of 1 with CoCp2 in a molar ratio 1:1 in n-pentane at -78 °C leads to the formation of 1,2-di-t-butyl-1,2-diiododiarsine (2) (t-C4H9AsI)2 in 69 % yield. The products have been characterized by spectroscopic methods (1H, 13C-NMR, EI-MS) and elemental analyses. The crystal structure of 2 has been determined by X-ray diffraction methods.

- Reactions of Iminotriorganylarsoranes in the Ammono System
-
The reaction of the iminotriorganylarsoranes 1-4 with potassium amide in liquid ammonia depends on organyl groups bonded to arsenic.As types of reaction nucleophilic displacement of organyl groups by amide ions and cleavage of arsenic-carbon bonds leading to alkene elimination are found.
