ChemInform Abstract: UMGRUPPIERUNG VON DIPHENYLAETHYLARSINOXIDEN

Abstract

Bei der Umlagerung des Arsinoxids (I) unter dem Einfluß von Halogenalkylen (II) entstehen vorzugsweise Ester der Diphenylarsinigsäure (III) neben den Diphenylhalogenarsinen (IV).

The reaction of triphenylarsine oxide with ethyl iodo‐acetate leading to triphenyl (carboethoxy)methylarsonium triiodide

“…It was also shown that the retro-Arbuzov reaction may take place in the series of tertiary trialkylarsine oxides or mixed alkyl(aryl)arsine oxides 1 (R = R = Et; R = Et, R = Ph; R = Ph, R = Et, Pr, Bu) by the influence of akyl halides 2 (Y = H, Me, Et, Pr; X = Br, I) [9][10][11][12]. Esters of trivalent arsenic acids 6 were isolated from the liquid part of reaction mixture with yields from 10 to 70%.…”

“…The formation of salts 4 was observed in a few cases. Adducts 5 may be formed by the interaction of salts 4 with the initial arsenic oxides 1 (reaction (2)) [10,11] …”
