Two diphosphines bearing an ethynylene and a 1,2-phenylene linkers between the sterically crowded triarylphosphine moieties have been synthesized by employing Sonogashira and Suzuki-Miyaura couplings as key reactions, respectively. Intramolecular int

The sterically crowded triarylphosphines bearing formyl and benzoyl groups were synthesized and characterized by X-ray crystallography. The benzoyl derivative was converted to the p -quinomethane conjugated with the triarylphosphine. The McMurry coup

In Japan, data on the epidemiological and clinical features of atrial fibrillation (AF) are rather sparse; even less data are available on the risk of thromboembolism in nonvalvular AF. The present study enrolled 19,825 patients who visited the cardi
