Bis(diphenylarsino)methane (1) gives only a monoquaternization product, 2, with methyl iodide but is converted into the bis(arsonium) salt 4 when methyl fluorosulfate is employed. 2 is the precursor for the monoylide MePh2As=CHAsPh2 (3) while 4 yields the first bis(ylide) (“carbodiarsorane”) MePh2As=C=AsPh2Me (5) on treatment with sodium amide in liquid ammonia at -40 °C. 5 is thermally unstable at room temperature but can be reprotonated with acid to give the corresponding dication of salts 4.
