Organoarsenic compounds containing

Cyclic and Polymeric Substances Containing Arsenic—Arsenic Bonds. A number of organoarsenic compounds containing rings of four, five, or six arsenic atoms have been prepared (cycHc polyarsines). The first such four-membered ring compound to be adequately characterized, tetrakis (trifluoromethyl) tetrarsetane [7547-15-17, was obtained by the interaction of a diiodoarsine and mercury (107,108) ... 

The pyrolysis of organoarsenic compounds containing the arsenyl moiety has some limited preparative applications [arsenyl (As=0) by analogy with phosphoryl (P=0)]. The compounds are based on the arsonic acid RAs(0)(0H)2, the arsinic acid R2As(0)0H and the arsine oxide R3As=0 structures. The acids are in interesting contrast with the phosphorus series. The phosphonic and phosphinic esters are prepared from the phosphorus(III) precursors via the Arbuzov synthesis. This synthetic route fails with the arsenic analogues, and further, if an alkyl halide or a salt is added in the pyrolysis of arsonic or arsinic acid esters a retro-Arbuzov reaction takes place . ... 

Primary and Secondary Arsines. Compared to the vast number of known organoarsenic compounds, relatively few primary (RASH2) and secondary (R2ASH) arsines have been described. Primary arsines are commonly prepared by the 2inc—hydrochloric acid reduction of substances containing... 

Relatively few organoarsenic compounds that contain an As-B bond are known. > > In most cases, these are synthesized by the straightforward reaction of the primary, secondary, and tertiary arsine with diborane or BH3 THF (equation 29). As-B bonding also results when the BH3 moiety reacts with Sn-As and As-P-As bonded compounds (equations 30 and 31). ... 

There have been several reviews that provide a comprehensive coverage of the synthesis and reactivity of organoarsenic compounds that contain tricoordinate arsenic with an As-N The acyclic aminoarsines,... 

The synthesis and reactivity of organoarsenic compounds that contain As-O bonds has been extensively reviewed. Because of space limitations, the extensive chemistry associated with As-O bonded systems cannot be covered. Instead, the highlights of the chemistry will be presented here and the reader is referred to the reviews for the vast quantity of more detailed information. These highlights have been grouped according to the more common classes of As O bonded compounds that serve as precursors to many of the compounds discussed in earher sections of this review. 

Ives and Guiflfrida ° investigated the applicability of the potassium chloride thermionic detector and the flame ionization detector to the determination of organoarsenic compounds in the presence of organophosphorus and nitrogen-containing compounds.
