ChemInform Abstract: ZUR FRAGE DES THERMISCHEN VERHALTENS VON QUASIARSONIUMSALZEN

Abstract

Durch Anlagerung von Alkylbromiden (II), (VI) an Trialkyl‐ bzw. Dialkylphenylarsinsulfide (I), (V) in Aceton bei 56 ‐ 57°C entstehen die Quasiarsoniumsalze (III) und (VII).

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 reactions of tertiary arsine oxides 1 with halogen-containing reagents 2 are reported to proceed in a complicated manner [6][7][8][9][10][11][12][13][14]. The directions of these reactions depend upon the substituents at the arsenic atom, the nature of electrophilic reagent, and the reaction conditions.…”
