(p-Nitrobenzylidene)triphenylarsenane, a semistabilized arsonium ylide has been prepared and reacted with carbonyl compounds to yield olefins as opposed to epoxidation products. Treatment of the ylide with a ranged acyl halides gave new disubstituted arsonium ylides. IR and NMR spectral data for the resulting products are reported.
