Sodium phenylarside and sodium-n-butylarside react with chloro (bromo) carboxylic acids and their sodium salts, amides or esters in liquidammonia to give the corresponding secondary arsino carboxylic acid derivatives. Their properties and reactions are described. In some cases the derivatives of arsindiyl-di-carboxylic acids are obtained as by-products due to transmetalation reactions.

characteristics in GaAs and Genanowires (NWs) are altered significantly following either indirect or direct exposure to a focused Ga+ ion beam (FIB), such as that used to produce Pt electricalcontacts to NWs. While these results challenge the assumptions made in some previously reported work relating to the electronic properties of semiconductor NWs using FIB-assisted production of contacts and/or their
