“…The backbone rigidity and the overall steric crowding at the Pd center seem to be more important than the chelate ring size in the determination of the catalytic activity. [32] The beneficial effect of the ligand rigidity on copolymerization reactions has also been confirmed by Doherty et al, with bis-phospholyl substituted carbon backbones. [33] Dossett et al provided experimental evidence that four-membered ring systems with i-propyl substituted phenyl rings exhibit high catalytic activity.…”

The creation of polymers with a high degree of sequence and/or stereocontrol represents an exciting frontier in materials science. In order to obtain alternating polymers, coordination polymerization using well-defined metal complexes has played a leading role in the last two decades. In the following paper, we will describe selected published efforts to achieve these research goals using discrete, structurally well-characterized metal complexes.

Alternating and Non‐Alternating Pd‐Catalysed Co‐ and Terpolymerisation of Carbon Monoxide and Alkenes

The co-and terpolymerisation of carbon monoxide and alkenes are usually catalysed by palladium complexes, and the properties of the produced polyketones can be finely tuned by an appropriate choice of catalyst and olefinic monomer. After a general overview of the topic, selected recent advances in this field are described. The use of palladium systems containing modified diphosphane and/or new phospho-

“…[1] As steric effects are crucial in the reactivity of metal-phosphane complexes, a good knowledge of the molecular structures of the species is required both in the solid state and in solution. [6][7][8][9][10][11][12][13][14][15][16][17][18] The performance of some of these branched polyphosphanes in catalysis, for instance, regarding C-C bond formation, [19,20] has driven progress in their synthesis.
