Substitution reactivity and structural variability induced by tryptamine on the biomimetic rhenium tricarbonyl complex.

ABSTRACT: A series of seven fac-[Re(CO)₃(5Me-Sal-Trypt)(L)] complexes containing tryptamine on the N,O 5-methyl-salicylidene bidentate ligand backbone and where L is MeOH, Py, Imi, DMAP, PPh₃ coordinated to the 6th position have been studied, including the formation of a dinuclear Re₂ cluster. The crystallographic solid state structures show marked similarity in structural tendency, in particular the rigidity of the Re core and the hydrogen bond interactions similar to those found in protein structures. The rates of formation and stability of the complexes were evaluated by rapid time-resolved stopped-flow techniques and the methanol substitution reaction indicates the significant activation induced by the use of the N,O salicyliden
