HPLC of Formula: C13H8O2. Recently I am researching about TRANSITION-METAL-COMPLEXES; KETONE ALPHA-ALKYLATION; ASYMMETRIC HYDROGENATION; BORONIC ESTERS; SIMPLE OLEFINS; VINYL ETHERS; RHODIUM; HYDROARYLATION; DIPHOSPHINES; HYDROFORMYLATION, Saw an article supported by the University of ChicagoUniversity of Chicago; NSFNational Science Foundation (NSF) [CHE-1855556]; Dalian Institute of Chemical Physics international talent training project. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Chen, XY; Zhou, XK; Wang, JC; Dong, GB. The CAS is 2005-10-9. Through research, I have a further understanding and discovery of 6H-Benzo[c]chromen-6-one
In contrast to the plethora of large-bite-angle bisphosphine ligands available to transition-metal catalysis, the development of small-bite-angle bisphosphine ligands has suffered from the limited structural variations accessible on their single-atom-containing backbones. Herein, we report the design and applications of a discrete very small bite-angle bisphosphine ligand, namely, FMPhos. Featuring a fluorene-methylene unit appended on the single-carbon linker, the ligand harbors an unusually rigid backbone that presumably stabilizes its complexation with transition metals during catalysis. Compared with the known dppm ligand, it exhibited superior reactivity and regioselectivity in a number of alkene hydrofunctionalization reactions, catalyzed by iridium and rhodium.
