Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 13991-08-7, Name is 1,2-Bis(diphenylphosphino)benzene, category: chiral-phosphine-ligands.
Synthesis and characterization of group 6 transition-metal [70]fullerene derivatives containing dppb ligands. Crystal structure of fac-Mo(CO)3(dppb)(CH3CN)
The thermal reaction of an equimolar quantity of fac-Mo(CO)3(dppb)(CH3CN) [dppb = 1,2-bis(diphenylphosphino)benzene] (1) with C70 in chlorobenzene at 80-85 C gave an isomeric mixture of fac/mer-Mo(CO)3(dppb)(eta2-C70) (2) in 46% yield, whereas the photochemical reaction of an equimolar amount of Mo(CO)6, dppb and C70 in chlorobenzene at room temperature afforded the isomeric mixture 2 in 48% yield and a single isomer mer-[Mo(CO)3 (dppb)]2(eta2,eta2-C70) (3) in 19% yield. Similarly, while the thermal reaction of fac-W(CO)3 (dppb)(CH3CN) (4) with C70 produced a single isomer mer-W(CO)3(dppb) (eta2-C70) (5) in 42% yield, the photochemical ‘one pot’ reaction of Cr(CO)6, dppb and C70 gave rise to a single isomer mer-Cr(CO)3(dppb)(eta2-C70) (6) in 62% yield and a single isomer analysis.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.category: chiral-phosphine-ligands. In my other articles, you can also check out more blogs about 13991-08-7
