New Reagents, XXXIV. (Diphenylarsino)methyllithium: Synthesis and Preparative Applications

(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.

In competition experiments with n-heptanal and diethylketone as substrates the reagents (CH3)2M(OiPr)3, CH3-MCl4 (M = Nb, Ta), and n-Bu-NbCl4 react exclusively or very selectively with the aldehyde.
