A mechanism has been suggested for the condensation of benzaldehyde with 5-pyrazolone. An explanation has been given for the formation of arylidene monopyrazolone compounds from dimethylaminobenzaldehyde and cinnamaldehyde. Cyclopropane compounds have been formed by the oxidation of 4,4'-benzylidene-bis-(5-pyrazolone) compounds with iodine. Original compounds have been obtained by the opening up of cyclopropane rings
