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.

New Reagents, XXV. lithium and -copper(I); Synthesis and Preparative Applications

lithium (1b), quantitatively obtained by organoelement-lithium exchange from bis(diphenylstibino)methane (1a), reacts with aldehydes and ketones to give (β-hydroxyalkyl)diphenylstibanes (2) (39 - 82percent).These compounds are now well accessible. copper(I) (5), quantitatively obtained by transmetalation from 1b, reacts with alkyl iodides to give alkyldiphenylstibanes (3) (45 - 80percent). (Diphenylphosphino)- (4a) and (diphenylarsino)(diphenylstibino)methane (4b) were obtained from 1b in unsatisfactory yields only.
