substituted cyclopropanecarboxylic acidamides with [(Ph3PAu)3O]BF4 (I) has been studied. The reaction of I with cyclopropanecarboxylic acid p-nitroanilide leads to the gold derivative with the AuN bond, the small cycle being unaltered. The interactions between lithiated cyclopropanecarboxylic acid N,N-diethylamides and I afford the organogold derivatives of the amides with gold bonded to the carbon of

(Z)-alpha,beta-enamides in which the C-C double bond is di-, tri-, or tetrasubstituted. In all cases the process is completely stereospecific and only a single diastereoisomer is obtained. In addition, cyclopropyl ketones were readily prepared by reaction of the cyclopropanecarboxamides (derived from morpholine) obtained with a range of organolithium compounds. A mechanism has been proposed to explain the cyclopropanation
