The electrochemical reduction of a series of compounds of two-coordinate phosphorus and arsenic with linear structure was investigated for the first time.The main polarographic characteristics indicate irreversibility of the electrode process and its complication by kinetic limitations.The products of controlled-potential electrolysis were analyzed, and schemes are presented for the electrochemical reduction, which consists in hydrogenation with cleavage of the P=E bond of most of the studied compounds (1,2, and 4) and in cleavage of the CAr-P bond in sterically hindered compound 3.The electrolysis products underwent further transformation in the presence of oxygen and moisture of air.Keywords: two-coordinate phosphorus; two-coordinate arsenic; electrochemical reduction; controlled-potential electrolysis; aprotic media; steric factors.

Aromatic primary phosphines react with carboxylic acid amide acetals to give aryldialkylaminoalkylidenphosphines.Intensive 1H, 13C and 31P nmr studies prove the compounds to involve phosphorus in the trivalent dicoordinate state.
