Bifunctional chelating molecules linking the fac‐[99mTc(CO)3]+ core with targeting biomolecules are required for the development of specific diagnostic radiopharmaceuticals. Diethylenetriamine (1) and N‐(pyridin‐2‐ylmethyl)ethane‐1,2‐diam

Two different pathways for the introduction of an acetyl group at N(epsilon ) in a N(alpha), N(delta), and -COO protected histidine to afford N(epsilon)-(CH(2)COOH)-histidine derivative 7 b are presented. The purpose of this study is the coupling of

A series of NS3-open chain and cage ligands were synthesised and their complexation behaviour towards Ag(I) and Cu(I) studied. Crystal structures show that all open chain ligands form complexes in which the four donor atoms of the ligands coordinate

The coordination chemistry of the heterofunctionalized phosphines HPN2 and H2PNO and of an analogue containing a relevant biomolecule, HPN-Pip (Pip = 4-(3-aminopropyl)-1-(2-methoxyphenyl)piperazine), was studied toward the synthon (NE4)2[ReBr3(CO)3].

The 5,5′-bis(hydroxyalkyl)-2,2′-bipyridines 4a–c (Scheme 1) were prepared either in one step (4b, 4c) or in four steps (4a) starting with 5,5′-dimethyl-2,2′-bipyridine in each case. Reaction of 4a–c with mesyl chloride afforded the bis(me

The potentially bidentate ligand diphenyl(2-pyridyl)phosphine (PPh2py) reacted with (NEt4)2[MIX3(CO)3] complexes (M=Re, Tc; X=Cl, Br) to give (NEt4)[MIX2(CO)3(PPh2py-P)] or [MIX(CO)3(PPh2py-P)2] depending on the amount of the ligand used. The reactio
