(Diphenylarsino)methyl iodide (3) was synthesized for the first time (76 percent). (Diphenylarsino)methyllithium (2), stable at 20 deg C, is accessible from 3 (ca. 100 percent) by iodine-lithium exchange with butyl- or phenyllithium and by organoelement-lithium exchange with butyllithium from diphenylarsane (4d; 92 percent). 2, prepared from 4d, gives far better yields of (diphenylarsino)alkanes by the reaction with alkyl halides than 2, obtained from 3.To the contrary, no difference is observed in the reactivity of 2 from 3 or 4d towards aldehydes and ketones.

Due to its ready accessibility and high nucleophilicity (lithiomethyl)diphenylarsane oxide (2b) is a favorable reagent for the synthesis of many organoarsenic compounds.In organic synthesis it is recommendable as a reagent for indirect nucleophilic halomethylations (Hal = Cl, Br, I).
