alcohols was studied at platinum and carbon anodes using quaternary ammonium nitrates and fluoborates as supportingelectrolytes. The most satisfactory conditions for the preparation of N-alkoxymethylalkylamides by this reaction involved the use of a platinumanode and a quaternary ammonium fluoborate. At a carbon anode, the major reaction is oxidation of the alcohol solvent to aldehyde, which is isolated

treatment (−78°C) of N-methoxymethyl–N-methylformamide and chlorotrimethylsilane with LDA affords synthetically useful yields of the carbamoylsilane. The latter undergoes silylgroupexchange at 145°C in the presence of a chlorosilane and CsF.
A process is disclosed for preparing phthalides by cathodic reduction of phthalic acid or phthalic acid derivatives, in which the carboxylic acid units may be substituted by units which can be derived by a condensation reaction from carboxylic acid units and in which one or several hydrogen atoms of the o-phenylene unit of the phthalic acid may be substituted by inert radicals. This process is characterised in that the reduction is carried out in an organic solvent which contains less than 50 wt % water and in a non-divided electrolytic cell.
