The present invention relates to cardiac tropism radiopharmaceutical products incorporating a nitride complex os a transition metal and having a rapid myocardial clearance. PAL These complexes are based on the formula: EQU (MN)L1 L2 (I) PAL in which M is a transition metal such as 99m Tc and L1 and L2 comply with the formula: STR1 in which at least one of the R and R' represents a branched alkyl group having one or more ether functions, a tetrahydrofurfuryl or ether group, a tetrahydrofurfuryl or dioxaspiro or dialkoxy piperidino groups.

The new process for the preparation of 2-nitrobenzaldehydes of the general formula STR1 in which X1 and X2 either independently of one another represent hydrogen or halogen or one of the substituents represents nitro and the other substituent then represents hydrogen, by oxidation of 2-nitrotoluenes of the general formula STR2 in which X1 and X2 have the meaning indicated above is characterized in that the oxidation with oxygen or an oxygen-containing gas is carried out in the presence of at least one alkoxyalkylamine as a solvent and in the presence of strong bases.
