α-Dialkylaminomethylphosphines and the corresponding arsines have been obtained by the following methods: (1) by direct Mannich reaction, (2) by reaction of secondary phosphines and arsines with bis(dimethylamino)methane, and (3) by reaction of methyleneammonium halides with secondary phosphines and arsines, silylphosphines and silylarsines, and alkali phosphides and alkali arsides, respectively.

strongly influenced by the nature of the positively charged group. We describe the coordination chemistry of the newly prepared α-cationic arsines toward different metal centers and their reactivity in the presence of strong oxidants to afford cationic As(V) species. Their unique electronic properties have been exploited in Pt(II) catalysis to develop a new catalyst with remarkable activity in the cycloisomerization
