Abstract
Bis-imidoylchlorides of oxalic acid react rapidly with magnesium shreds in dry THF under ultrasonic conditions to give 1,5-naphthyridine derivatives a nd the isomeric indigodianiles. Using a cross-over experiment the existence of key intermediates corresponding to dimeric isocyanides could be verifie d.
