Webknown. In this coordination mode, two inter-complex angles can be considered to investigate the flexibility of the dpaH ligand: (1) the pyridine nitrogen –metal– pyridine nitrogen (N py–M–N py) bite angle; and (2) the pyridine centroid–amine nitrogen–pyridine centroid angle (Py cent–N a–Py cent). A scatter plot of these two Web19 jun. 2024 · Having access to small bite angle bisphosphine complexes that were capable of binding amine–boranes, albeit made in situ, their ability to dehydrocouple H 3 B·NMe 2 H was evaluated, as we have previously shown that the P–Rh–P bite angle has an influence on the rate of this process. 7 The dehydrocoupling of H 3 B·NMe 2 H in …
