considerable difficulties were encountered in the preparation of fulvene dialdehydes needed for the synthesis of novel porphyrin analogues. These problems were overcome by reacting protected iodofulvenes with magnesium ate complexes at low temperatures, followed by addition of DMF and hydrolysis. The thiophene-containing fulvene gave good yields of the dialdehyde at −78 °C or −100 °C, but the furan system
