Abstract The synthesis and characterisation of acyl-thiol end-capped homobimetallic rigid-rod structured molecules of type [(MeC(O)S 4-NCN)Pt ← N C C6H4 C N → Pt(NCN 4-SC(O)Me)](OTf)2 (6, NCN = [C6H2(CH2NMe2-2,6)2]−) and (MeC(O)S 4-C6H4 C6H4)(Ph3P)2Pd ← C5H4N CH CH C6H4 CH CH C5H4N → Pd(PPh3)2(C6H4 C6H4 4-SC(O)Me)](OTf)2 (9) in which the metal fragments are spanned by π-conjugated organic connecting
Kinetico-mechanistic studies on the formation of seven-membered [C,N]-platinacycles: the effect of methyl or fluoro substituents on the aryl ancillary ligands
The rate determining step for the formation of seven-membered platinacycles from cyclometallated Pt(iv) aryl complexes is determined by the nature of the substituents on the aryl groups.

conversion to the protein-pincer metal complex hybrid was obtained in 48 h. The NCN-pincer metal phosphonic acid derivatives (3, 4) appeared to be inactive as cutinase inhibitors. In contrast to our previous work which entails propyl tethered phosphonate esters connected to pincer metal complexes, the presented strategy allows positioning of metal complexes inside the activesite of lipases. This opens up

Synthesis and characterization of bioorganometallic conjugates composed of NCN-pincer platinum(II) complexes and uracil derivatives
the formation of the NCN-pincer platinum(II) complex bearing the 6-ethynyl-1-octyluracil moiety. The NCN-pincer platinum(II) complex bearing the furanopyrimidine moiety was obtained by the reaction of the NCN-pincer ligand bearing the furanopyrimidine moiety with [Pt(tolyl-4)2(SEt2)]2. The single-crystal X-ray structure determination of the NCN-pincer platinum(II) complex bearing the furanopyrimidine
