of various quinolones and pyridones. The C-H activation reaction proceeded with high site- and enantioselectivity (14 examples, 83-97% ee). Key to its success is the use of a chiral phenanthroline ligand that is attached via an ethynyl linker to the 8-position of octahy-dro-1H-4,7-methanoisoindol-1-one. AgPF6 (10 mol%) served as the silver source, PhI=NNs as the nitrene precursor and 1,10- phenanthroline
emission spectra of the complexes demonstrated that the CT interaction between the π-electron system in the phenligand (π(aryl)) and the vacant p orbital on the boron atom (p(B)) in the DBDE group (i.e., π(aryl)−p(B) CT) participated in the excitedstates of the complexes in addition to the Ru(II)-to-phen metal-to-ligand CT (MLCT) interaction. Reflecting such synergistic MLCT/π(aryl)−p(B) CT, both 4BRu2+
Abstract A general protocol for the coupling of mono- and dihalo-1,10-phenanthrolines with diethyl phosphite is reported. This reaction proceeds smoothly in the presence of a Pd(OAc)2/dppf catalytic system and triethylamine as a base. A general protocol for the coupling of mono- and dihalo-1,10-phenanthrolines with diethyl phosphite is reported. This reaction proceeds smoothly in the presence of a
