ACS Appl Mater Interfaces. 2013 Jun 12;5(11):4731-8. doi: 10.1021/am303253p. Epub 2013 May 16.

Potassium ions are successfully intercalated into WO3 nanobundles with the integrity of the pseudo-orthorhombic structure remaining intact. The nanobundles display a 5-fold increase in the electrical conductivity. It changes from a value of 10(-4) Sm(-1) for pure WO3 to...

Enantioselective Rhodium-Catalyzed Coupling of Arylboronic Acids, 1,3-Enynes, and Imines by Alkenyl-to-Allyl 1,4-Rhodium(I) Migration.

Angewandte Chemie (International ed. in English)

Callingham M, Partridge BM, Lewis W, Lam HW.

A chiral rhodium complex catalyzes the highly enantioselective coupling of arylboronic acids, 1,3-enynes, and imines to give homoallylic sulfamates. The key step is the generation of allylrhodium(I) species by alkenyl-to-allyl 1,4-rhodium(I) migration.

Exploring new reactivity of metal nitrides is of great interest because it can give insights to N2 fixation chemistry and provide new methods for nitrogenation of organic substrates. In this work, reaction of a (salen)ruthenium(VI) nitrido complex with various...

Iridium-catalyzed arylative cyclization of alkynones by 1,4-iridium migration.

Angewandte Chemie (International ed. in English)

BACKGROUND: Burkholderia pseudomallei is an emerging pathogen that causes melioidosis, a serious and potentially fatal disease which requires prolonged antibiotics to prevent relapse. However, diagnosis of melioidosis can be difficult, especially in culture-negative cases. While metabolomics represents an uprising...
