(Halomethyl) Arsenic Compounds. I. Primary and Secondary (Halomethyl)Arsines.

摘要

(Chloromethyl) arsine and bis(chloromethyl)-arsine were prepared by the reduction of (chloromethyl)arsonic and bis(chloromethyl)arsinic acids,respectively. (Bromomethyl) and (iodomethyl) analogs of the primary and secondary arsines could not be prepared because of a facile rearrangement from C-functional to As-functional halides. Reactions of ClCH2AsH2demonstrated a strongly reduced affinity for proton-proton exchange with hydrogen halide (in comparison to CH3AsH2), a reduction anticipated by group-electronegativity considerations. Nmr,ir,and mass spectral data are included.
